A vacant inherited house, by itself, is a sleepy list unless you are sufficiently skilled to isolate and stimulate their pain.You need better lists which target people with big, in-their-face problems. 

IF you know how we could find or better tune our search to isolate builders that would be wonderful!

To make a long story short: Our tenants reported that the main circuit breaker has been tripping with some frequency, so we brought an electrician out today.He isolated the problem: romex wiring outside the house going to the central A/C unit.

HUD does not isolate and identify any issues

(not sure if this works since I'm not 'pro') - BP rental calc has it avg $4,680/yr (for 1100 rent), even though I put the same exact numbers/expenses, etc as in my spreadsheet...not sure what I'm missing or how that number is really calculated4-Plex:Expected Purchase Price: 250kUnits: 4 (MFH)This is a recently rehabbed building, so no other upfront costs neededAll units are rented at 850 per unit, per month = 3,400/month (supposedly there is a wait list too, which I will be sent tomorrow)Location is not the greatest (no crime issues, just in a more isolated location.

If we isolate each additional bedroom past 4 and look at the bedroom ROI in a vacuum that's a 96% return, or 2,000 % Cash on Cash (house hacking with 5% down) for each additional bedroom past 4 you can find / create in a single family home.

The home was ~30 miles from a hospital, isolated on 3 acres.

I only ask because if this was one isolated incident, it is possible their offer was better up front, but negotiations dropped it back down. 

Isolating land value is a process of reverse engineering all the expenses required for the development, building & improvements from the value of a completed building.Just remember when you are essentially buying dirt, you are buying negative cash flow until you can cross the river from idea to income producing.  

However, I'm currently in the military at a VERY isolated location so I don't really have the opportunity to check out the local market (nor am I really interested in buying up here).
