I probably DEFINITELY spend WAAAYY too much time designing kitchens, houses, decks, trim, bookcases, you name it.

I just looked it up for FL; carpentry/framing 15.91%. carpentry/trim, interior 8.44%.The reality is you're competing with others using unlicensed/uninsured "contractors".

Also trimming any trees or vegetation. 

New electric, hvac, new kitchen, bath, windows, doors, trim, add closets.

After it is installed securely and sealed up, I would just use trim on both the interior and exterior to cover up the gap that was framed and insulated!

I have trimmed my 'stash so I am not munching on it.

i am not selling the rentals as they bring in cash flow except when repairs are high, which they usually are, this year was very expensive as i needed 2 basements with wall support work and one also needed waterproofing, @ $7,500 each and lucky to get that price, plus $10,000 in roof and gutter work plus over $5,000 in general maintenance after tenants moved or city inspection, all together over $30,000, so  thats why I am now interested in flipping, as it may take several years just to  break even with the rentals,  my credit is good except for the many loans and credit cards, which i always pay on time,  I have some good contacts in Jackson, Mi for plumbing, furnace, tree trim, electrical etc, and now basement and roofing, so  I could organize many repairs in that general area to start, but am open to any state

Full gut with new Electrical, Plumbing, HVAC, Windows, Floors, Drywall, Appliances/Cabinets and trim your looking ball park of $100K.  

In all areas I have worked, it is a z bent aluminum trim, that you make with an aluminum break to keep anything broken from falling out the bottom...you can get a ton of colors to do this with to.

A reasonably proficient handyman who knows how to work with drywall, trim carpentry, tongue-in-groove subflooring, natural stone tile would see this property as a gold mine.
