Many real estate investors opt for a fix-and-flip loan because they’re relatively easy to obtain: no personal income verification (no DTI requirements), and you can often borrow up to 90% of the purchase price and 100% of the rehab costs.

Whereas owner occupant buyers are looking at comps, sold prices for similar nearby properties, and don't care about cash flow. 

Do you have a price range and are you looking for turn-key properties or something along the lines of a "fixer upper"?

Flipping a brand new home likely wouldn’t bring much profit - especially after having to close twice when you first buy it, and later sell it.Maybe you have millions to spend and I’m just missing the big picture… but when I think of “income” I’m usually thinking “net income” after you factor in expenses, like purchase price or building costs?  

@David F.As Russell mentioned co-ops are probably 1/2 the price of a condo and you would also have extensive costs to set up a co-op and typically it’s my understanding the builder funds the first 1-2 years of reserves.

What makes me nervous is his hasn't sold yet for the $495,900 price.

You may want to make an introduction between your CPA to those 2 colleagues.The CPA can go over their services and pricing to your colleagues.I partner with many people on real estate deals - It never gets to a discussion on whether they do their own tax return or hire a professional.If a partner mentions he will provide capital - does he provide the capital on a timely manner.If a partner mentions he will find deals - does he find many deals and provide an analysisIf a partner mentions he will manage a property - does he manage the property well(find tenants, collect rent, communicate with contractors, etc)

However, prices for a comparable 5-bedroom home in Washington are significantly higher, likely around $1.5M or more, which would mean taking on a new 30-year mortgage with 6+% interest rate and limiting new investment opportunities.2.

There's also discussion of intentional inflation, but is there any impact on real estate prices at all?

In fact the demand is stronger than I've ever seen it, though prices are high.
