The middle unit is 3 Bed/1 Bath & inherited rent is wayyy low at $1300.

There is strong wage growth, low unemployment and the economy appears to be performing well. 

I have loan officers that will do under 4 units as low as $40,000.Let me know if you need help finding a different mortgage broker.

Therefore, I'd get 1/4 inch lag bolts and drive them through the plywood right into the door frame to secure the property while you find a contractor.Since I have no idea about your area, I'd start at Home Depot/Lowe's.

The situation he is in is a mess where he does not want to sell because he keep getting low ball offers and he'll lose money selling with an investor he told me.

What system is everyone using to keep track of property information such as insurance premiums, maintenance records, age of the A/C, etc.

I just believe the 200k cash offer is waaaay to low.
