There are so many other ways to purchase whereby you could have more square footage/dollar than a traditional purchase would provide.

The only time you should add square footage or extra bathrooms is that the comps demand it.

Start by grouping the comps you do get using two qualifiers:1 - Within no more than 2 square miles of eachother.2 - The square footage must be within 10% larger and/or smaller than any property you are analyzing to buyDon't group multiple properties of different sizes and take the average square footage. 

Other things to consider: age of subject, improvements needed in future, townhouse you have the board to consider and you cannot expand, single family you can add an ADU unit for more income or add square footage.

Plus, you're closer to The Smokey Mts/Gatlinburg/Pigeon Forge which have been a relatively unknown destination for vacation until recent years.

I owned and lived in duplexes and triplexes, in Queens, moved from one to the other, so I know what you're talking about.For a duplex, for tax purposes, you allocated 50% to the rental, or prorate using another percentage for the rental based on a square footage.

When you refinance you will be taking out cash on the appreciation/equity at 75% LTV unless its a primary then you can go up to 90% CLTV.If you buy a home for example and convert a garage to a bedroom or build additional square footage multiple bedrooms/bathrooms/bigger home GLA.

Are we able to deduct the total utilities etc for this home on a % basis of the square footage?

The govt section 8 program doesn’t care about the sq footage size, only that it has 4 legitimate bedrooms with closets, windows, doors.
