I will implement this strategy as soon as I get past this initial phase. 

We plan on having the phone tracking implemented within 2 months as long as all goes well with testing.  

The bigger issue is that we are only able to offer low cash offers on homes and are trying to implement seller financing and subject to offers for sellers who want more than the low cash offer.

To me, that sounds like the fairest and simplest to implement as those agencies already have the infrastructure to handle such a program, they just may need to scale a bit but not maybe as much as one would think. 

With those below market rental rates, the Gross Potential Income in year 1 of operation is $975,719, and we implement rental increases once we hit 60% occupancy. 

This is a serious problem, and unless you learn really, really fast, you'll end up being taken to the cleaners as you implement contractors' and inspectors' wishlists without the discernment to realize what is needed and what isn't. 

Its a strategy and can be implemented on various lines of credit whether residential or commercial, however the best products to utilize this strategy with are the All-In-One (AIO) loan or with commercial lines of credit since they use the purest forms of simple interest. 5) Can a simply concept of simple interest versus compound interest actually make that much of a difference?

The strategies I implement in NYC may not be effective in Jersey.

Now I just need the time to finish it up and implement their suggestions.

A plan suggested by others at this point is useless to you without the back ground knowledge required to implement it.Read, listening and learning for now.
