From a Multi-Family Specialist and 30-Year Licensed General Contractor Who Inspects Investment Property Like He’s Going to Own It Himself
Buying an investment property is a different exercise than buying a home to live in. You’re not just asking if you’d enjoy living there. You’re checking whether the numbers make sense, whether the building needs unexpected repairs, and whether the current tenants have been treated fairly. I’ve spent thirty years as a licensed general contractor and I still walk every investment property I show a buyer the way I’d walk one I was about to buy for myself. Here’s what I actually look at, broken into the physical side, the financial side, and the tenant side, before any offer goes in.

Start with the building, not the spreadsheet
I start by checking the property’s physical condition, not just the rent roll and cap rate. Those numbers matter, but a new roof or failed sewer line can quickly wipe out your expected returns. I’m looking at the roof’s age and remaining life, the condition of the foundation and any visible settling or cracking, the age of the water heaters and the furnace or heat pump systems, and the state of the electrical panel. Older properties, which make up a lot of the rental stock around Salem, often have a mix of updated and original systems, and knowing which is which changes how you should be pricing your offer.

Deferred maintenance is a negotiating tool, not just a red flag
Every property has some deferred maintenance, the question is how much and how it’s priced into the deal. A cracked driveway or dated paint is cosmetic and can usually wait. A roof with a few years of life left, a water heater past its expected service life, or siding showing early rot are different, those are costs you can reasonably estimate and should factor into your offer or your request for repairs or credits. Because I’ve built and remodeled property for decades, I can usually give a buyer a realistic sense of what a repair is actually going to cost, rather than a vague “that’ll need work eventually” that doesn’t help you negotiate.
Review the rent roll against real market rent
On the financial side, the first thing I want to see is the current rent roll, meaning what every unit is actually paying right now, compared against what similar units are renting for in the current market. A seller may assume rents will reach market rates as soon as you take over. But rent increases have legal limits and timing requirements. Re-leasing a vacant unit at a higher rate also takes time and money. I want to understand the gap between current rent and market rent, and how realistic it is to close that gap, before I treat a pro forma number as if it’s already happening.

Dig into the expense history, not just the income
It’s easy to focus on rental income and gloss over expenses, but a full year or two of actual expense history, not just an estimate, tells you a lot more about what you’re really buying. I want to review utility costs when the owner pays them, property tax history, insurance costs, and HOA or shared maintenance fees. I also want to know how much the owner has spent on repairs in recent years.
A property with little recent maintenance may look like a bargain. However, it could need major repairs soon after you close.

Understand the tenants you’re inheriting
Buying an occupied investment property means you’re also buying the landlord-tenant relationship that already exists. I want to see the actual lease agreements, not just a verbal summary, so I know the rent amount, the term, who’s responsible for which utilities, and any special terms the seller agreed to. I also check how the seller handled security deposits and whether they will transfer correctly at closing. Oregon law sets specific rules for tracking and returning deposits. I also want to know how the seller has treated the current tenants. Long-term tenants who pay reliably and take care of a property are valuable, and a seller who’s been a decent landlord often hands you a smoother transition than one who’s let things slide.
Ten things to check before you buy investment property
- Roof age, condition, and estimated remaining life.
- Foundation condition and any signs of settling or water intrusion.
- Age and condition of water heaters, furnaces, or heat pumps.
- Electrical panel age and whether wiring has been updated.
- Current rent roll compared to realistic market rent for each unit.
- At least one to two years of actual expense history, not estimates.
- Copies of all current lease agreements and their terms.
- How security deposits have been held and whether they transfer properly at closing.
- Property tax history and whether a sale could trigger a reassessment.
- General tenant history, including payment reliability and how long tenants have stayed.
A practitioner note on title and access
One thing buyers sometimes overlook, because it’s not a defect you can see on a walk-through, is the title report. I always want a buyer to review the preliminary title report closely for easements, shared driveways, or access agreements that affect a multi-unit property, especially anything around shared parking, shared utility lines between units, or boundary questions if the property has ever been divided or combined. These issues rarely kill a deal, but they can affect how you manage the property and what you’re responsible for maintaining, and they’re much easier to understand before closing than after you own it.

Why this matters more in multi-unit property
Everything above gets more important, not less, as you move from a single rental house into a duplex, triplex, or fourplex, since more units mean more leases to review, more systems to inspect, and more cash flow lines to verify. The upside of more doors is that losing one tenant has a smaller proportional impact on your total income, since the remaining units are still generating rent while you re-lease the vacancy. That stability is a big part of why multi-unit property appeals to investors, but it only holds up if you’ve actually verified the condition and the numbers on every unit, not just the one or two the seller walks you through.
Serving buyers across the Mid-Valley
I help investment property buyers do this kind of due diligence across Marion, Polk, Yamhill, Linn, Benton, and Clackamas counties, so wherever in the mid-valley you’re looking, I can likely walk the property with you and tell you what I’m actually seeing.
Frequently asked questions
Should I get a professional inspection even if I’m buying with an experienced investor’s eye?
Yes, a licensed inspector should still be part of your due diligence, a knowledgeable walk-through adds perspective but doesn’t replace a formal inspection and its written report.
How far back should I ask for expense history?
One to two years of actual expenses gives you a much more reliable picture than a single year or a seller’s verbal estimate, and it’s worth asking for documentation, not just numbers on a sheet.
What if the seller won’t share full lease agreements before I make an offer?
That’s worth treating as a caution sign, you want to review actual lease terms, not a summary, before you’re too far into the transaction to walk away comfortably.
Can I just raise rents to market rate right after I buy?
Not always immediately, existing leases and any applicable notice requirements affect timing, so confirm what’s actually allowed for your specific leases and situation before you count on that income in your numbers.
Does the physical inspection matter as much on a newer property?
It matters less in terms of major system replacement, but I still walk newer properties carefully, since construction quality varies even in newer builds.
If you’re about to make an offer
If you’re getting ready to buy an investment property and want a second set of eyes on the building and the numbers before you commit, I’m happy to walk it with you and talk through what I’m seeing.
