I am unwilling to accept a purchase price reduction in the amount of $10,000 because of how highly leveraged I am.

I wanted to know what equations/metrics are a MUST HAVE when looking at a possible deal - I'm having a hard time trying to pin down which hold the most weight and make the largest impact in the rental world!

What about a price reduction or an incentive of some sort to get your house sold to a qualified buyer?

There is a high likelihood they are but a few simple risk reduction actions and you can check whether their sob story is real or not.

Either way you can’t  predict those dynamics and purchase and sale transactions in my opinion should put a lot more weight on price.

My reasoning is that I like having a lower required monthly payment in order to maximize my monthly cash-flow.Remember, you can always reduce your principal balance at any time with a HELOC (or an loan for that matter) simply by making a, "principal reduction" payment.

But now that I've found the BP calculators, I'm in love...and so is my financial planner, if for no other reason, it takes some of the weight of telling me "No" off of him because I can see for myself that it's a bad deal. 

Would it be better to add in clauses to the lease or would an addendum signed by the tenant hold the same weight.

It might sound expensive but this is off the books money and that carrys a lot of weight to me, not having my credit dinged or showing a brand new loan on my credit report bringing the score down when i go to finance it long term is a huge help if your financing in your own name.

After all this plus mortgage  payment reduction ( I typically only lay 20% down), I require a minimum of a 30% cash on cash roi.
