My principal balance right now is about 187K.

I've not heard of Investor's Edge, but definitely look at the backgrounds (resumes/Linked In profiles) of the principals to see what they did in the past. 

Right, I'm trying to not refi since I'm knocking down principal 50-60k a year but I may need to increase cash flow in the near future.

You will then have a few options with that rent money....you can put it into principal or you can start saving it to purchase yet another property.

This includes principal, interest, taxes, homeowners insurance and mortgage insurance!

But she wanted to know if she can deduct the principal amount that she paid to the person off of her taxes since she has to report the interest as income. 

This is a major drawback for depreciable assets.Hoping you have a good CPA in your corner my friend!

Working with a hand saw is a lot safer..I am financing 3 larger deals at 7.45% now with a 20 year amortization and a 3,2,1 pre-payment penalty, which is important, because we are going to pay down the principal a little faster and probably will refinance in a couple of years, depending on what rates we see.You have to look at interest rates in the context of inflation, rents and home price appreciation.

You have no flexibility when it comes to exit strategies with only one building/project.They both have advantages and drawbacks.

You are assigned a crack CPA, with an accounting assistant who are overseen by a ProVision principal.
