As long as you don’t present them as concessions you could do things like 1) say you are planning to do it in 60 days but as a courtesy could extend that to 90 if that makes a difference (holidays etc) and 2) if YOU think an upgrade of something is warranted say you will be spending the first X of the increase on a new whatever.

If your mortgage was warrantable then your building won’t allow short term rentals.

In the 30s, public opinion turned against anything over two units, so finding newer multis is a really binary search - either 1914 or 2014 (since the past decade as Boston approaches peak population again has turned favor back to housing density, and rents warrant the cost to build).

Being anxious or having emotional issues should not warrant a dog in my opinion .

One day while in retirement they were all out fishing but waiting for them at the shore were police with a warrant for their arrest for negligence, do not become on of these kinds of flippers.

I have a potential deal where 2 multi family units produce enough to warrant a 600k price. @ a cap of 7.5%.

Meaning that the rents don't seem like they warrant the asking prices nor would they allow for any cash flow after running our expenses. 

And of course your area may be different in terms of cost and also some jobs don't require a full cosmetic renovation, but most of mine have.Then of course check the big ticket items like HVAC, roof, exterior siding/masonry repair, windows, interior sheetrock replacement, foundation and water heater and know approximately what it will cost to fix/replace each if warranted.  

Does this warrant any type of civil lawsuit?

Typically, if it meets the 1% rule, then it warrants a deeper look.
