I recommend documenting everything with the damage through photos, videos, etc. before cleaning up. 

Section 8 Homeownership Vouchers (TOTAL) DefinitionSection 8 Homeownership Vouchers refer to housing subsidies received under the Housing Choice Voucher homeownership option from a Public Housing Agency (PHA).Required DocumentationThe Mortgagee must verify and document the Borrower’s receipt of the Housing Choice Voucher homeownership subsidies.

Getting less every month is still generally more cost effective than dealing with a tenant that stops paying or causes damages to the property.However, if you do decide to change your selection criteria and you are worried about fair housing, the main thing is documentation.

My question is, can I legally rent this space?

I did go on the website and none of the HUD inspection or landlord documents were even able to be downloaded and viewed.

(Also, caveat to make sure this is all legal in your state as each is different)One - they are going to move out and leave a ton of stuff behind.

It's also good for insurance and legal reasons, because you will need to indicate every adult and all persons, as well as details (like children, pets, etc.), on the lease.  

Study HOA documentation prior to purchase as rental restrictions can limit the usage as an income property, especially when HOA is non-cooperative.

Many times, they provide these types of documents for their members.

The question I have, is there a legal way to assume the mortgage since he has such a great rate?
