Just had all new HVAC installed and still needs 35K of work.

There is also currently a new 4 BR septic being installed, and there is also an in-law apartment downstairs.I estimated repairs at $20,000 by experience I've had in the past doing construction and home improvement and I can also probably do 90% of the work myself unless there are plumbing,electrical, foundation or other major issues beyond my skill set.I used zillow's comp tool to give me an estimate of what the house is worth and zillow says $365,933, which seems a bit crazy to me but who knows.

I plan on buying my own shingles and having a roofer install to save on some money.

Tenant has been planning to install fire system and sprinkler system which will cost them $30,000.

Looking for a good recommendation for a fair handyman or contractor to install lamps, sinks and toilets for my new condo rental.
