@Joshua DorkinIs correct - this will get much more customized over time.

If you know the original balance of the loan and origination date, you can make some assumptions for interest rate and length of the loan and generate an amortization chart.

Roughly 25% of that $1500 is lead generation, so the contractor has passed the savings on to you.

Most of my customers are City folk looking to purchase their county homes.

My wife plans to get back to work to help generate us more cash to eventually buy a property.After a long winded intro, we are in a situation where we have roughly $75k-$100k in equity if we sold our home.

I've replaced 3 in the last year - two of which had to be engineered custom systems (30k+ not fun).

My question is how much of a price change should generate qualified tenant calls?

It sounds like what you have done in the past with your customers is similar to what I will be doing with someone in my local market. 

You are in business and you have a disgruntled customer.

Intrinsic benefits might be your ability to use a property as additional collateral in another transaction, it might be some community benefit that makes you a hero in your community, good will, or generating other business opportunities.A good investment is one that doesn't cost much to get into, doesn't present headaches, that cash flows to pay for itself, doesn't eat any hay, and appreciates in value!
