Few banks will give home equity lines to houses that aren't owner-occupied but Wells Fargo will.

However, if that were the case, builders who are already buying down rates aggressively would be selling more homes, but they aren’t.

If it were free and easy, everyone would be doing it and the competition would keep you from participating.If you aren't willing to invest some money, time, and effort into the hard things, you aren't going to reap the rewards.

You aren't raising rents because you don't want to lose your tenants?

Showmojo is MUCH more customizable, to the point of being very intimidating if you aren't a professional property manager.

If there aren't any good comps in the area, I would move on and not take the risk.

@Isadore Nelson why aren't you using the BiggerPocket Calculators?

There really out of there depth aren't they.

If there aren't any, start one.  

Most of them aren't you!
