I have the scope of work which totals around 80k, possibly more because I just found there is a water leak in the main line 😢I was wondering if I can fix the other units (total work ~20k-25k) and sell with the last unit still distressed. 

Roof, swimming pool, interior, exterior, driveways, landscaping, etc.

If the LLC is an operating business..... lets say providing roofing services with annual revenues that are consistent or even better increase year after year for 10 years, lines of credit or other lending options might be available that aren't available for a new business. 

How are the major potential expenses of the house looking (AC, Roof, Plumbing, Electric)?

My main concerns about Florida include: Chinese Drywall (very toxic; found in older homes); HOA Restrictions; Lots of people/crowds; sinkholes (properties sinking into the ground); Red tide (dead fish found on beaches due to algae bloom); Homeowners Insurance costs (w/older roofs); Mold; Hurricanes/Flooding , New construction (not always built to quality)... these are the most common issues found in the Florida market.What zip codes would you recommend for a single family investment property under 300k to mitigate these concerns? 

. - We’ve also inspected the roof / parapet wall, but don’t think those are the culprit because the issue presents itself on the 2nd story, not the 3rd story that’s immediately below the roof. - Plumbing issues have been ruled out.

For roof-mounted solar, you need a roof that is oriented well and gets good solar exposure in order to produce power.

The reason I am ok with that is because I just spent $140K and updated everything - electrical, plumbing, roof, HVAC, windows, etc. so costs should be minimal for a while.

The roof was also a problem since it had wood shingles and apparently that is way more costly.

If you need to replace the roof).
