Here is a tip I have been able to take advantage of on a few fix and flips that made me an extra $15-20K, especially if you have a good contractor. Anytime you have a covered patio with a concrete floor you may want to take a look at the expense of adding three walls and finishing it off to add more square footage. Typically the cost/ft^2 will be 1/3 of an addition because the foundation, roof and one wall are complete, and if you are in an area where homes sell fore more than $100/ft^2 an average 20X20ft^ patio could easily add $40K to the ARV and cost less than $15K to complete. This works especially well on smaller <1000ft^2 homes that you can get cheap due to their smaller size.
Hope this helps!
