Then, try to adjust for square footage, and features, etc.

Armed with this new information (to divide a lot up, and sell a parcel for income) I began to scour the MLS through Zillow’s map feature - and putting in minimum lot square footage at 10,000 ft.

I personally don't like them but they have great square footage and we've found many of them in some really solid older neighborhoods. 

The building right next door to mine pays $25k even though it is very similar in style and condition but far larger in every way (twice as many units as mine, almost twice the land acreage and building square footage).

The sun room didn’t count towards the sq footage of the home, but we want to be sure this area is now counted towards it.

One contractor told me that no one uses licensed contractors in the flipping business unless they're adding square footage.

When you say adding square footage, you mean adding an ADU?

If that's the case, you'll need to post at least the square footage, #Beds, #Ba, #garages and give at least a neighborhood.

I recommend looking at other rentals in the area, similar location, bed/bath count, square footage, and condition.

You could do a hard money loan: buy the home, add sq footage and an ADU and then refi into a 30 yr loan once the home can be rented out to cash flow. 4.
