I have purchased a property with a house on it that won't be able to be rehab'd because of the extensive termite damage and wood rot. 

Left a mess and damaged a lot of things, vandalized and everything.

Your lucky the family helped.At first they wanted me to do it , I reminded the daughter she was also on the lease and responsible  for  damages and the clean out costs .  

So far I have had the boys strip a roof (used contractor to put on the roof) - resulted in boys in landfill jail for not having the cash (I did not know no credit cards) - boys claim there were 7 layers, take down 2 large trees, add 3 sister boards to a garage rafter, build 2 fence segments including an 8’ high fence, add dumpster stops to concrete to prevent fence damage, add privacy screen to a chain link fence (took surprisingly long - hog rings really do not work well), remove and rebuild a privacy partition on to a wall, rehang a gate with better hinges, weed an abandoned yard (unit caught fire in oct and due to Corona work has stopped - slightly wet winter and weeds were 4’ tall), plant a new citrus tree.  

Also take lots of photos to document the damage.

Have you ever given a tenants deposit back too early and then discovered damages upon further review?

However, proposal does not include repairing sheetrock walls or ceilings, damaged or removing during the installation of Vertical Wall Restraints.My questions (since I know NOTHING about foundations, rehab):1.

I have personally found that Real-Estate backed Private Notes / Loans are the most secure way to invest your funds for any duration you so choose, at an interest rate WAY better than the banks, or bonds, with monthly "dividends" and still secured by an actual physical asset!

Try not to damage relationships.
