One of the stipulations for the sale was to provide effort to remove 2 problem tenants in the building.

However, you likely have a stipulation in your contract (or should ask for one) where they communicate with you first about repairs over $300 and you can definitely ask for multiple bids if you're looking to do something like replace an HVAC system.  

I too offered agents the ability to offer the renovations without any upfront cost to the sellers and we would get paid at closing, of course this requires some documentation that stipulates that can not back out of the listing and other protections since we would have our money tied up into their home.

Notice how many of the major MFU Complexes have those stipulations in their leases?

I'm not a realtor, so we are not allowed to use the GAR forms, and their forms often contain a non assignment stipulation.

It's more of a replacement for the security deposit as they only cover guest damages with some specific stipulations.

The general thought is that the loan was originated with all FHA stipulations met at that time of creation. 

I  know that there are certain stipulations that come with the grant and I want to use  FHA  loans to keep my down payments low.

.- We will stipulate that this is hypothetical. 

The loan we were applying for is an FHA, which stipulates we must provide a signed lease for our half of the duplex (to be newly rented out) but for the other half which the parents "own" (in reality all three are equally owners of the entire property.) we would need to provide proof of rental income on our tax return, however her parents claimed that so we seem to be SOL.The mortgage is covered, we can rent it out no problem, but the underwriter is saying on paper it looks like she is responsible for the whole duplex and the rent for half of it is unreportable.
