Well, I live where the forced air systems serve both heating and cooling.

Onciously it depends on the size of the house, and attic space.  

A lot also has to do with the size  and growth of the bank.

Technically if you have a decent sized upstairs you can turn your basement into one with a small amount of plumbing and electrical work.  

A large building with a common hallway serving several units....you better have a pretty detailed and specific Dr. note on file outlining the health issue to the tenant.

The bank is served so they know the tax foreclosure is happening and they have the opportunity to redeem and pay the taxes to protect their position.

I'll start off by saying believe in the power of CL (craigslist) I don't let a day pass   without utilizing that site.my advice to you would be log on CL search area's within a 2hr distance from you go under real estate fsbo filter your search with we buy house's or I buy ugly house's and investor special,once you find these ads start making phone calls,reason being these investors know their local market and have their hands on the pulse of that farm area.After dissecting all the useful info from local rei,I generally go to google streetview and walk the neighborhoods to have a better understanding of there market.Trust me it works I just closed 3 wholesale deals in Birmingham,Al using those same techniques,I was fortunate enough to find a we buy house's sign on a street corner zoomed in on the sign called the number and almost 2 months later the deal was funded.I hope this post serves you willCheers!

age, location, size, and cost of replacement are all major factors for insurance, unfortuantely your purchase price doesn't matter too much!

Because of the extenuating circumstances, I would not serve the "Pay Rent or Quit" notice immediately, but I also would not go past mid month before doing so.
