In the under $400k price point I'd look at Fairfax, Alexandria (not the brick garden buildings, but newer buildings) and Springfield.

I had to go to zoning and spend thousands to get it legalized.Your situation seems as if it is zoned as a single family home, and it was split into 2 apartments with no building permits.He's selling the property because he has the wrong zoning, and is finding a bank or an investor who over looks the problems that will arise once they close.With the way things are with insurance, I wouldn't be surprised if your insurance company will not insure for two unitsgood luckGino

It is better for us to move the tenants out whenever we take over a building that has rents that are way under market.

Do this for a year or two and build up more cash, and then do it again.
