Of course you need to verify and then ask what requirements are need such as square footage, roof pitch, foundation type etc.  

Other than zip code your other factors that will play a large part in the rates are your credit score, your claims history and the properties claims history, Age of home and age of mechanicals, number of units, square footage, properties intended use(short term vs long term rental). 

At least 51% of the square footage within the building must be residential.6.

I believe that the square footage is limited to 800 or 900 square feet. 

NOw those are great rentals.. you can hardly hurt them and to do a turn over cost very little.. one bathroom one kitchen.. little square box.they have zero curb appeal .. but as a pure rental.. when you look at some of the other ones i looked at  bigger houses big sq footages those are going to lose money over time in the rental game. 

Your home has decent square footage in comparison, but will seem smaller if there is more stuff in it.

So with current square footage of about 2,900, that leaves me with $290,000 in repairs.

Similar square footage and bedrooms.

Split it based on number of bedrooms or square footage. 

Do the county record/MLS square footage accurately reflect the extra room?
