Black cabinet hardware and changing to a black sink to match the other appliances would look nice though and wouldn't cost much

The biggest concern they are having is over dramatically increasing costs...not so much with rate, but with items like taxes and insurance.

I currently have 5 mortgages but have not been great at keeping track of the details such as costs associated with each individual property.

But you will increase costs in regards to insurance or lending..You still risk losing the property to any liability that happens at the property or in your personal life.

This takes seconds and costs pennies to run the reports for hundreds of thousands of loans.

Depending on how much of a discount you are buying the property at, it might make more sense to just wait the 90 days that most lenders want you to own it before refinancing it, in order to get your basis in the property as low as possible. 

Has anyone on here done something similar and remember the cost or have an idea of what pricing should be (ballpark)? 

on the bleachers right now just learning so i got a question If I find a  duplex for 350k, put 20% down , 30 year mortgage after the 30 years is over and the property is paid off,  it cost me more than 700k that just doesn't sit right in my stomach.

Could be an absolutely gigantic cost and ruin the deal for you, or could be small.
