Regarding used mobile homes, you'd have to inspect them to see what issues and/or repairs are needed.

If you feel you need to do an inspection to know around how much cost it will take to rehab, then I would grab a contractor friend for a rough est, and tell your buyer the APPROX repairs needed.

Bought an auto repair shop for 30% of value because of environmental problem.  

The total loan amount for the purchase and rehab can't exceed 75% of the after repair value of the property.

If a landlord needs to enter a property for an inspection or repair, a two-day notice is required.

You should be approving repairs of that expense every time.

I just bought my first rental property, and it came with a pool that needs some repairs that could be fixed.

Can easily be repaired. 

Hello BP community,I have given termination of lease to end this month to a Sec 8 tenant who violated the lease with subleasing, damage, and failure to cure and repair damages est. $35,000.

If you have the means to hold the property, make the repairs to the foundation and wait for up swing in the market, I would try to hold it.
