You might be able to convince seller to let you out for even or something but if you still like the property and want to hold on you need to get alternative financing in place because this seller seems unlikely to actually grant the extension.

Alternatively, you or your realtor could visit the building department to confirm whether or not a permit was issued for this work in the garage.

I help investors “unlock” their IRAs and 401Ks to be able to invest in alternative assets such as real estate.

I’m considering as an alternative to buy a large single family and rent per room.

How will these various alternatives perform in the future?

Wanted to get thoughts on redevelopment options - looks like everyone is building retail ground floor and apts above but wanted to get thoughts on micro units and condos as alternatives. 

Or alternatives to get the ~$25k cash that will not disqualify me for the FHA construction mortgage?

Do not spray or they will look for an alternate way out of the nest which likely is a way into your house. 

I'm concerned that multifamily on the open Market in this are getting to expensive to be a good first buy.I may look for wholesale properties or foreclosure as an alternative for value buys.  

Alternatively you can learn from your own mistakes but it can be costly and traumatizing for some folks.
