Does anyone know where I can find good construction contract to give me protection for my Rehab work being done up to standard ,and my completion due dates being meet on time ?

It's a bit higher than most conventional loans, but it also doesn't go on your credit report and the loan can go as a LLC for liability protection. 

properties are in llc and I just want to know any benefits and tips moving forward. I'm a newbie !

I would like to do this in a way that as much as possible of the gains from these sales is protected from capital gains taxes, so if anyone has advice on how to do that, it would be appreciated. 

The good news is that she has no lease and nothing to protect her.

Don't waive contingencies or decline certain protections, like a home inspection.

Better protection is an arc-fault breaker, because arcing from missing insulation is one of the dangers of K&T.As for insulating, obviously anything that looks like it is loose or coming apart I would re-wrap with good quality electrical tape (electricity off, of course, when you do this) but beyond that you want to keep combustibles away from the wiring. 

What types of insurance do most investors make sure that they have to protect themselves and their properties against lawsuits / claims from tenants?

When you have more assets or a larger company, states like Delaware, Nevada, Wyoming may make sense if you are looking for charging order protection, anonymity, business friendly case law, etc. 

For me personally, in addition to the extra protection the LLC provides, there is a law that prevents us from having more than 10 conventional mortgages under our personal names.
