This reply made my day.Off the top of my head, I am assuming the two concerns/issues one would have would be the set-back requirements (Not a big deal) and parking space requirements (Could be a big deal depending on the lot size.

The only other answer is a forcible eviction and that can be time consuming and expensive depending on your state.

Regarding the house hack method,  depending on what kind of work the building needs,  I would recommend hacking the basement/ lowest floor unit first.  

It was a tough decision to commit to my local market with my duty station only having a population of 30,000 and being heavily dependent on the military. 99.99% was overpriced.

I'd need to charge $50-100 each time depending on location and can put that into a buyer's agreement as an additional charge to you at a future closing.

Shane,I guess it depends on how you are going about the rehab.

Depending on the stage of a pre-foreclosure your approach would need to be different.

This will vary depending if you include only hard costs or add soft costs, land and financing.  

I'd be interested in taking a look at your condo as a purchase as well depending on location, etc in town.

I don't think there are too many hard money lenders out there lending more than 95-97% LTV which is where your conventional/FHA loans are going to max out depending on your scenario.
