Also, I do understand that there are many variables to my question such as interest rates, etc but any insight on good areas where rents keep increasing would be appreciated.Thanks in advance for any advice!

That is variable as well.

I believe there are too many variables for that kind of model to work.

A general credit line, on the other hand, could be secured by other assets or unsecured, and doesn't necessarily involve your home equity.HELOC Characteristics: - Uses your home as collateral - Usually has a lower interest rate than unsecured credit lines - Typically has a variable interest rate - Allows you to borrow up to a certain limit, repay, and borrow again during the draw period - Can be used for various purposes, including home improvements, debt consolidation, or as an emergency fund While it's possible to use a HELOC for RE investing or rehab projects, some lenders may be hesitant about this use.

Too much risk and variables for me.

The rate is variable, and you could really move the needle on debt paydown if you throw a ton of that cashflow at the loan. 

If they are getting 1 month's rent per turnover (for unknown & varying # of turnovers) plus upcharges as they call the Maytag man for every little fix (unknown # per year) there are a lot of variable costs. 

There have been a number of syndications that have quit paying dividends as of late because they were tied into variable interest rate financing, and as the Fed raised rates there wasn’t enough money left over to pay dividends.  

There are too many variables here.I look at P&L and balance sheet and the total package of the deal.

But there are a lot of variables they will consider in figuring out your loan will be structured.1) Is your land owned free and clear and if so how much of it will they allow you to be credited towards the project down payment.2) Have you done any loans with them before?
