Obviously it keeps the payment low, I'm sure I could always pay more each month.- I know you would need more information to give an educated opinion of the deal, but just looking at the rough terms what are your thoughts?

Personally I will only rent yo someone with a government voucher in the very low end neighborhoods. 

Low property taxes in city.So many deals, so little time!

Now, I know the object is to keep expenses low and profit high, but could a few simple additions increase your bookings?

That seems extremely low to me.

Have any of you considered or do any of you put that money into a CD equal to the length of the lease so you can gain a significantly greater amount of interest on that money you will hold onto for the foreseeable future rather than letting it sit in a low yield savings account.

If it is really low, I would take a look at the aggregate cost of your debt once adding the HELOC.

We're finding plenty that allow for low down payment financing, including FHA.  

We got low interest and had the money in 2 days.

I'll use myself as an example.I wouldn't call myself a master salesman (not in-person, anyway) - but I am pretty good at finding properties at a very, very low price.
