  • Owner statements every month
  • Licensed vendors only
  • No markup on repairs

About the firm

A small office, on purpose.

Most owners come to us after the same experience: a big management company, a portfolio manager who changes every spring, and a repair bill nobody can explain. We built this practice to be the opposite of that. We keep the portfolio small enough that we know every roof, every furnace and every tenant by name.

That means we sometimes turn work down. If a property is outside our service area, or the numbers only work if we cut corners on maintenance, we will tell you and point you somewhere else. Owning a rental in Portland is a long game, and the buildings that hold their value are the ones that get looked after early.

If you are deciding whether to keep a property, sell it, or hand it over to someone else, come talk to us first. The first conversation costs nothing and usually saves you a season of guessing.

Why choose us

Four things owners notice in the first month

01

You get a person, not a queue

Your calls and emails go to the same manager every time. No ticket numbers, no portal that answers with a template.

02

Repairs are billed at cost

We do not mark up vendor invoices or take a cut of the work. You see the original invoice attached to your statement.

03

We price the block, not the city

Rent recommendations come from listings within walking distance of your property, adjusted for condition and parking.

04

Tenants stay longer

Turnover is the biggest cost in a small portfolio. Responsive maintenance and fair renewals keep good tenants in place.

Portland

We work where we live.

Portland is not one rental market. A 1920s bungalow off Alberta rents on a different logic than a 1970s fourplex in Beaverton, and inner southeast turns over on the school calendar while the west side follows employers. Knowing that difference is most of the job.

We stay inside a radius we can drive. If a request comes in at four o'clock, someone can be at the property before dark — and that is only true because we do not manage buildings two hours away.

Testimonials

From owners we work with

We inherited a duplex and had no idea what we were doing. They walked us through the numbers, told us which repairs could wait, and had it leased inside a month.

Owner, inner southeast duplex

The statements are readable. That sounds like a low bar, but after two other companies it was the first time I could tell where my money went.

Owner, two single-family rentals

A pipe let go on a Saturday. Someone answered, a plumber was there that afternoon, and I got photos before I had finished worrying about it.

Frequently asked

Questions owners ask first

What do you charge?

Management is a percentage of collected rent, and leasing is quoted separately. The rate depends on the property type and number of units. You will have it in writing before anything is signed, and it does not change mid-year.

How fast are maintenance requests handled?

Routine requests are dispatched the next business day. Anything involving water, heat, gas or personal safety is treated as urgent and handled the same day, including weekends.

How do you screen tenants?

We verify income, confirm rental history with prior landlords, and apply the same written criteria to every applicant in the order applications arrive, consistent with fair housing requirements.

Do you manage outside Portland?

We work within roughly a 30-minute drive of the city, which covers Beaverton, Milwaukie, Gresham and most of the close-in suburbs. If your property is farther out, we will refer you to someone closer.

Can I switch to you mid-lease?

Yes. We handle the notice to your current manager, collect the lease files and deposits, and introduce ourselves to the tenants. Most transfers take two to three weeks.
