Assuming FHA or VA loan at lower rate , although I need to cover current equity in home?

If you're hoping to wait until interest rates come down, not only do we have no clue if or when that will happen, but when it does you may see prices go up as buyers are able to get larger loans.

So I will get money that is being considered goods and services rate not the cash advance rate.

Here is a historical chart comparing the two:The reality is that a drop in interest rates virtually never make prices go down, they are inversely related. 

Others may disagree, but I would highly recommend paying off all of our debt and increasing your savings rate before investing. 

With the WSJ Prime Rate in the 8%s, you're probably in the 9%s on your line right now (just an assumption).

I'm thinking of keeping the 2bedrooms at the current rate. 

Folks get caught up on losing their interest rate.

.- Perhaps you think rates are going to move lower.

You cannot spend too much time on any one door because you cannot charge beyond the market rate for any single door, so each door needs to follow the process efficiently and precisely.
