If you make improvements to a property (garage or another type of remodeling or addition) those items will also be added to your cost basis and affect your capital gain or loss. 

I'm just about done remodeling one of the houses and it's rented. 

The other units we gutted to studs and totally remodeled and leased out for a higher market rate.  3 weeks ago I started the process to refi (I paid cash. 

I just sold a house last year that we did a major remodel on, I know an extremely good realtor, and I know a foundation guy whose company also does some flips so I am better prepared than many.

So i walked in to take a look.Overall its pretty nice most of the interior has been remodeled.

can I get some references for good GC who can work on flipping properties end to end for remodeling?

I have a couple I work with, but need to have more for move out punch lists, remodels, and tenant calls.

I project manage now, which isn't necessarily easier or better, it's just more efficient with my time as I have other businesses that generate revenue, including new construction/custom remodels and a thriving real estate agency business.Contractors have always been the biggest challenge for me in the business. 

From the contractor side, I've remodeled a few vacation rentals in the Bushkill/Stroudsburg area.

I've gotten different suggestions: either conduct a basic remodel of the kitchen and bathroom, or undertake an extensive gut and remodel and convert the kitchen + living room to one large open space (that came from one of the GC's who does flips in the area).
