And you only get charged on the HELOC on the money outstanding. 

By running the numbers on their side, their bank is charging them a 4.5% interest for the HELOC, which after running numbers, they are basically having to come out of pocket to pay their interest for their HELOC. 

Then put them on notice that if it breaks again, you will pass the charges on to the renters.

I haven't seen expenses charged to specific units (i.e. only the upper floors and not the bottom floors).

Are the tenants in charge of lawn/snow? 

We also get a security deposit and charge a larger cleaning fee for long term stays.

Is there any standard practice to break TCC something like      Site preparation and other works 4-6%,            Service works 14-19%,        Finishing works 20-25%,       Civil works 50-55%,            Consultation charges 3-5% of Total Construction Cost estimations?

Account Closed  Unfortunately none that I have found to be legit, or charged too many fees, or didn't have the capital I needed.I've been doing rehabs for quite a few years now and ultimately starting working with local banks that could provide purchase + rehab financing all in one loan.

I’ve worked with my GC on several deals and he has approached me about wanting to work together.Essentially it would work something like this…1) My LLC purchases the property2) He will only charge me COST on the labor and materials (no profit or markups) which will save me around 30% on regular contract figure he gives me in my market which is very expensive3) He will also make 300k of his own liquidity available to inject into the deal (I will put some of my own cash in and get a HML loan for the rest).

This is also something that those awesome "GURUS" don't tell you in their books, videos, and programs, and it is that their are so many different moving pieces in a deal and especially in Pennsylvania it gets more complex as they will charge you taxes for both sales, even if it is an assigned contract.
