If you're talking about investing in New Construction versus existing houses, and not GC'ing new construction then your lenders won't care about your construction background. 

Is KNOWINGLY increasing a payoff to an amount ABOVE what was technically and verifiably owed illegal for the lender and or borrower to do?

I’m technically in Natick, but that wasn’t an option.

Some background I am 21 years old and in my Jr. year of college.

Hi Seth, your GC background is gold for BRRRR in Columbus!

.: I ALWAYS do a background check. 

Am I allowed to use a private investigator to do a background check on potential tenants, WITHOUT letting the potential tenant know?

So it isn't a complete waste, you would simply need to follow the strict reading of the law with no private clauses for consideration...I'm not sure how that plays out since technically if the lease is void, so is the tenancy meaning you could terminate anytime and not wait for the original lease expiration...I'm sure that's covered somewhere, but again I'd ask my local atty what to do given this is such a locally specific issue. 

We have already done all the work from remodeling, furnishing to all the technical/software stuff.

I am thinking I would like to start with a duplex/triplex/quadplex but I am open to your suggestions.I really enjoy making money and have been in technical sales for more than 30 years.
