Turning Your Home Into a Rental in Oregon: A Clackamas County Guide

The short answer: Turning your home into a rental in Oregon works on two clocks at once. Conventional financing will generally let a signed lease on the home you are vacating help you qualify for the next one, counted at 75 percent of gross rent and netted against the full payment. FHA is far stricter. Separately, Oregon rent and termination law applies to you from the first tenancy.

What Changes When You Keep the House: Turning Your Home Into a Rental in Oregon

The day you move out and hand someone else the keys, three things change at once, and only one of them is about the mortgage.

First, the property stops being your principal residence and becomes an investment property in the eyes of the agencies. Fannie Mae's occupancy topic defines an investment property as one owned but not occupied by the borrower, and that reclassification drives how future financing on the house gets priced and underwritten.

Second, the rent becomes income a lender may or may not let you use. That is the piece that decides whether you can afford the next house.

Third, you become a landlord under Oregon's residential landlord and tenant law. There is no version of this where you keep the house, collect rent, and stay outside that chapter. Most of the surprises I hear about later live in this third bucket, not the first two.

Your existing loan does not have to change. A mortgage originated on a property you genuinely occupied stays in place when your circumstances change afterward. What matters for the lender is your actual intent at the time you applied, which is why the honest sequencing below is worth reading before you sign anything.

How Lenders Count the Rent When You Are Turning Your Home Into a Rental

On a conventional loan, the rules live in Fannie Mae Selling Guide topic B3-3.1-08. Because a converted principal residence is a property placed in service in the current calendar year, the guide lets your lender use a fully executed lease rather than a Schedule E from a tax return you have not filed yet.

The lease alone is not enough, though. It has to be supported by an appraisal form showing market rent, which is Form 1007 on a one-unit property or Form 1025 on a two- to four-unit, or by evidence that the lease terms have actually gone into effect. For a newly signed lease, that evidence means copies of the security deposit and the first full month's rent check with proof of deposit. Your lender will also pull Schedule E from your most recently filed return to confirm the property showed no rental income or expenses before now.

Then comes the haircut. Gross monthly rent is multiplied by 75 percent, and the remaining 25 percent is treated as absorbed by vacancy losses and ongoing maintenance. That is not a lender being conservative on you. It is the published calculation.

The part that surprises people most is what happens next. Since the house is no longer your principal residence, the qualifying rent is netted against the full PITIA on that property. PITIA means principal, interest, taxes, insurance, and any association dues. If 75 percent of the rent exceeds the full PITIA, the difference is added to your income. If it falls short, the shortfall is added to your monthly obligations, and the full payment on your new home counts as an obligation on top of that.

So the useful question is not whether the rent covers the mortgage payment. It is whether three quarters of the rent covers principal, interest, taxes, insurance, and dues together. On an older Milwaukie or Oregon City house with a low rate, it often does. On a newer Happy Valley house with high taxes and an HOA, it often does not.

Departing Residence Rules: FHA and Conventional Differ in Oregon

If you are buying the next house with an FHA loan, the answer changes sharply, and this is the single most useful thing on this page for a Clackamas County move-up buyer.

HUD Handbook 4000.1 addresses rental income from other real estate holdings directly. Where that income is derived from the property being vacated by the borrower, the handbook requires that the borrower be relocating to an area more than 100 miles from their current principal residence. It also requires a lease of at least one year's duration running past closing, plus evidence that the security deposit or first month's rent was paid. Where there is no rental history since the previous tax filing, the lender must obtain an appraisal evidencing market rent and showing that the borrower holds at least 25 percent equity in the property.

Read that 100 mile requirement against a map of Clackamas County. Milwaukie to West Linn is roughly ten miles. Oregon City to Lake Oswego is about the same. Nowhere in Tu's service area is 100 miles from anywhere else in it. In practice, that means an ordinary move-up inside the county will not let you use the departing home's rent on an FHA purchase. You would need to qualify carrying both payments on your own documented income.

That is often the reason a file that looked fine on paper flips from FHA to conventional. It is worth knowing before you write an offer rather than after.

Program requirements change and every file is different. Treat this as the shape of the rules, not as your approval. Eligibility is subject to underwriting and credit approval and a full loan estimate. The handbook language above comes from the published copy of HUD Handbook 4000.1, which carries a last revised date of August 14, 2019, so confirm the current text with your lender before you rely on it.

Turning Your Home Into a Rental in Oregon Starts a Landlord Clock

Here is where accidental landlords get caught, and it has nothing to do with lending.

Under ORS 90.323, you may not increase the rent at all during the first year after the tenancy begins. Whatever number you write on that first lease is your rent for twelve months, so setting it casually because the tenant is a friend of a friend is an expensive habit. After the first year, you need at least 90 days written notice, you may raise rent only once in any twelve month period, and the increase is capped.

The cap itself comes from ORS 90.324, which sets the annual maximum as the lesser of ten percent or seven percent plus CPI. For 2026 that maximum is 9.5 percent. The Oregon Department of Administrative Services publishes the following year's figure by September 30 each year, so if you are modeling a hold past this year, you are modeling against a number that has not been published yet. Scope your projections accordingly.

Your notice also has to say specific things. ORS 90.323 requires the notice to state the amount of the increase, the amount of the new rent, the date the increase becomes effective, and, if you are claiming an exemption, the facts supporting it. A landlord who raises rent in violation of the cap is liable to the tenant for three months' rent plus actual damages. That is the number worth remembering.

One exemption is worth checking before you assume the cap binds you. Under ORS 90.323(5)(a), a dwelling unit whose first certificate of occupancy was issued less than 15 years before the date of your rent increase notice is not subject to the percentage cap. If the house you are keeping is newer construction, and a lot of Happy Valley stock is, read the 15 year rent cap exemption guide, because the clock runs from the notice date and a building ages out of it.

The Rent Cap Exemption Oregon Accidental Landlords Actually Get

There are two widely repeated beliefs about small landlords in Oregon. One is false and one is true, and people usually have them backwards.

The false one is that owning a single rental house exempts you from the rent cap. It does not. ORS 90.323 contains no small landlord exemption, no single family exemption, and no owner-occupancy exemption. One house, one tenant, and the same 9.5 percent ceiling applies to you in 2026 as applies to a management company with four hundred units.

The true one is narrower and lives in a different statute. When a landlord terminates a tenancy for a qualifying landlord reason, ORS 90.427(6)(a)(B) normally requires paying the tenant an amount equal to one month's periodic rent at the time notice is delivered. Subsection (6)(b) says that requirement does not apply to a landlord who has an ownership interest in four or fewer residential dwelling units subject to the chapter.

So if the house you kept in Oregon City is your only rental, you are very likely inside that four-or-fewer group and would not owe the relocation payment. You would still owe the notice, the reason, and the supporting facts. The exemption covers the money, not the process.

If the home you are keeping sits inside Portland city limits rather than in Clackamas County, a separate city ordinance layers on top of all of this, and Portland's relocation rules are not shaped like the state's. My Portland versus Clackamas County landlord rules guide walks the jurisdiction line, which is drawn by city limits rather than by county or mailing address.

Selling the Rental Later Is Harder Than Clackamas County Owners Expect

This is the constraint almost nobody prices in, and it is the reason I ask people how long they actually intend to hold.

Once a tenant has been in the house past the first year of occupancy, ORS 90.427(3)(c) says you may terminate a month-to-month tenancy only for a tenant cause or for a qualifying landlord reason. The qualifying reasons are a short and specific list in ORS 90.427(5)(a). Demolishing the unit or converting it to a non-residential use. Repairs or renovations where the unit is unsafe or unfit, or will be during the work. You or an immediate family member moving in as a primary residence, provided you do not own a comparable available unit in the same building. Or accepting an offer to purchase from a buyer who intends in good faith to occupy the home as their own primary residence, with written evidence of that offer provided along with the notice.

Each of those takes 90 days written notice. The buyer-occupant path can drop to 60 days under ORS 90.427(5)(b) if you pay the tenant one month's periodic rent at the time you give notice.

Notice what is missing from the list. Selling to another investor is not a qualifying landlord reason. Neither is simply deciding you would rather have the equity. If your plan is to rent the Milwaukie house for three years and then sell it vacant to whoever pays the most, Oregon law does not hand you that option cleanly once the tenancy passes its first year.

There is a genuine tool here for people who are unsure. During the first year of occupancy you may end a month-to-month with 30 days notice and no stated cause, and a fixed term lease that ends inside that first year can be terminated with 30 days notice before the ending date. Also worth knowing, ORS 90.427(1)(a) defines the first year of occupancy to include all periods in which any of the tenants has lived in the unit for one year or less. If you are testing whether landlording suits you, structure that first lease with the exit in mind rather than discovering the rule in month fourteen.

Should You Refinance Before Turning Your Home Into a Rental?

Usually the answer is that if you were going to do anything with that loan, the window is before you move out, not after.

The mortgage insurance question is the common one. The federal framework for cancelling private mortgage insurance is built around what 12 U.S.C. 4901(15) calls a residential mortgage transaction, meaning a loan secured by a single family dwelling that is the principal residence of the borrower. Your servicer will also have its own requirements for evidence that value has not declined. Practically speaking, scheduling an appraisal is easier in an empty house than in one with a tenant and a lease, so settle it early. My guide to removing PMI with a refinance covers the routes, and the refinance guides hub covers the rest.

One thing I will say plainly. Any refinance you apply for as an owner occupant has to reflect your genuine intent at the time you apply. If you already know you are moving out and renting the place, say so and let the file be priced for what it is. Occupancy on a loan application is not a formality.

Later on, once the house is a rental you do not live in, different doors open. A cash-out refinance on an investment property carries its own ceilings and seasoning expectations, which I cover in the cash-out refinance on a Clackamas County rental guide. And if your personal income will not support another payment, a DSCR loan, short for debt service coverage ratio, qualifies the property on its own rent instead. Just remember that a DSCR loan underwrites to rent while Oregon caps how fast rent grows, which is exactly the interaction I walk through in Oregon's rent cap and your DSCR loan.

If the house has an accessory dwelling unit, or has room for one, that changes the arithmetic again. The financing rules for an ADU depend heavily on whether you still live on the property, which is the subject of my ADU financing guide.

Where Turning Your Home Into a Rental Pencils in Clackamas County

The move-up pattern I see most often runs from Milwaukie and Oregon City up into West Linn and Lake Oswego. That direction is what makes this strategy work, because the departing house is the more affordable one and the payment on it is usually modest relative to the rent it commands.

Older stock helps. A house bought in Milwaukie several years ago with a smaller loan balance, modest taxes, and no HOA has a real chance of clearing 75 percent of market rent against full PITIA. That is the arithmetic that makes the next purchase possible.

Newer stock is harder. A recent build carries higher assessed value, higher taxes, and often association dues, all of which sit inside PITIA and none of which the rent haircut forgives. It can still be a fine long term hold. It just may not help you qualify today.

For a sense of what the departing house is likely worth and what the entry-price segment looks like, the Oregon City housing market report is the closest read I have on the county seat. On the buy side, West Linn and Lake Oswego are where most of these move-up files land, and both frequently involve jumbo financing on the new house while the old one becomes the rental.

The Order I Recommend for Turning Your Home Into a Rental in Oregon

1. Price the departing house honestly. Full PITIA on one side, a realistic market rent on the other, then take 75 percent of the rent and see what is left.
2. Decide the loan type on the new house early. If the answer needs to be FHA, plan on qualifying without the rental income, because an in-county move will not meet the 100 mile requirement.
3. Handle any refinance or mortgage insurance removal while you still live there. It is simpler, and the appraisal is easier to schedule.
4. Get the lease and the deposit documented properly. Executed lease, security deposit, first month's rent, proof of deposit. Your underwriter will ask for all four.
5. Set the first year's rent deliberately. You cannot raise it for twelve months, so the number you pick is the number you live with.
6. Structure the first lease around your exit. If you are unsure about holding long term, the first year of occupancy is when you have the most flexibility.
7. Bring in the right professionals. A real estate attorney for the lease and the notice forms, a CPA for the tax treatment of a converted residence. I handle the financing, and those two questions are genuinely theirs.

Twenty years of doing this in Clackamas County has taught me that the people who do well keeping their first house are the ones who decided to be landlords on purpose. The ones who struggle are usually the ones who backed into it because selling felt like a hassle. Both start the same way. Only one of them reads the rent notice rules before month thirteen.

If you are working through the earlier version of this decision, buying a rental outright rather than converting one, start with buying your first rental property in Oregon. The full set of investor guides sits on the resource library, and the loan programs hub covers the purchase side of the next house.

Frequently Asked Questions About Turning Your Home Into a Rental in Oregon

Can I use the rent from my old house to qualify for my next home in Oregon?

On a conventional loan, generally yes. Fannie Mae Selling Guide topic B3-3.1-08 treats a converted principal residence as a property placed in service in the current calendar year, so a fully executed lease may be used, supported by Form 1007 on a one-unit property or Form 1025 on a two- to four-unit. Gross rent is counted at 75 percent, and that figure is netted against the full PITIA on the property. On an FHA loan the answer is usually no for an in-county move. Eligibility is subject to underwriting and credit approval and a full loan estimate.

Why does FHA have a 100 mile rule for the home I am vacating?

HUD Handbook 4000.1 allows rental income from a property being vacated only where the borrower is relocating to an area more than 100 miles from their current principal residence, along with a lease of at least one year's duration past closing and evidence the security deposit or first month's rent was paid. Where there is no rental history since the last tax filing, the lender must also obtain an appraisal showing market rent and at least 25 percent equity. Since a move from Milwaukie to West Linn is roughly ten miles, an ordinary Clackamas County move-up will not clear that requirement.

Does Oregon's rent cap apply if I only own one rental house?

Yes. ORS 90.323 has no small landlord exemption and no single family exemption. For 2026 the maximum increase is 9.5 percent, calculated under ORS 90.324 as the lesser of ten percent or seven percent plus CPI. You also may not raise rent at all during the first year after the tenancy begins, may raise it only once in any twelve month period, and must give at least 90 days written notice. A landlord who violates the cap is liable for three months' rent plus actual damages.

Am I exempt from the relocation payment as a one property landlord in Oregon?

Very likely. ORS 90.427(6)(a)(B) requires a landlord terminating for a qualifying landlord reason to pay the tenant one month's periodic rent at the time notice is delivered, but subsection (6)(b) exempts a landlord with an ownership interest in four or fewer residential dwelling units subject to the chapter. Keeping one house in Oregon City would ordinarily place you inside that exemption. It covers the payment only. The notice, the stated reason, and the supporting facts are still required.

Can I sell the house later if I have a tenant in it?

It depends on how long the tenant has lived there. After the first year of occupancy, ORS 90.427(3)(c) permits terminating a month-to-month tenancy only for a tenant cause or a qualifying landlord reason. Accepting an offer from a buyer who intends in good faith to occupy the home as their primary residence is a qualifying reason under ORS 90.427(5)(a), and requires 90 days notice with written evidence of the offer, or 60 days if you pay the tenant one month's rent at the time of notice. Selling to another investor is not on that list, so plan your exit before the tenancy passes its first year.

Should I refinance before or after I turn my home into a rental?

Generally before, if you were going to refinance at all. The federal framework for cancelling private mortgage insurance is built around a residential mortgage transaction as defined at 12 U.S.C. 4901(15), meaning a loan on a single family dwelling that is the borrower's principal residence, and an appraisal is far easier to schedule in an empty house than in a leased one. Whatever you do, the occupancy you state on an application has to match your actual intent when you apply. Once the property is a rental, a cash-out refinance or a DSCR loan become the routes worth comparing.
