* Assure that persons with disabilities are able to live free from intimidation and harassment; and * Require that multi-family housing built for first occupancy after March 13, 1991, has certain accessible features (e.g., a usable kitchen for a person who uses a wheelchair).The Fair Housing Act prohibits housing providers from discriminating against applicants or residents because of their disability or the disability of anyone associated with them and from treating persons with disabilities less favorably than others because of their disability.

Since FHA loans are only given to owner occupant homebuyers, if you were hoping to use the FHA loan to purchase an investment property, your question becomes moot.The FHA loan guidelines are more relaxed than conventional loan guidelines; this includes less strict regulations about past bankruptcies and/or foreclosures, job requirements, use of alternative credit, and debt-to-income ratios.

-The property must be stabilized at 90% occupancy for 3 consecutive months to be considered.

Therefore you will have to go through the eviction process and on the legal forms (for a name)  you will put "All Occupants". 

After foreclosure the new owner will have to visit the property to determine occupancy.

The property was used as a two-unit rental prior to the foreclosure, in a town that has gov't officials who say that there are already too many rental units in the town So they have some ordinance that says that any property reverts to a single family when that property goes over 1 year without being used and having a valid certificate of occupancy.

We would need to either offer it as storage with a lease clause prohibiting occupancy or just keep it inaccessible to the tenants. 

Best to wait out the two year ownership and occupancy period and take all your profit tax free.

Since rehabbed inventory is at serious low for owner occupant buyers, they rehab to the absolute minimum to make it FHA eligible with lightening speed.

Occupancy really depends on several factors.
