I talk a lot about opportunity cost and long term outlook here in the forums, so let's compare the two strategies over the next 20-30-years:You could stay in your interest only loan and enjoy better cash flow, to the tune of an extra $450/mo in your pocket.

Agree with @Michael Hacker, the extra weight might be your biggest concern. 

Typically, no extra cost, if there is town pick up.

I don't know if you're telling the truth, giving us all the information, etc.If you have not committed a crime or violated your lease, then the judge will rule in your favor.

It takes 45 days or more to close with a 203(k) due to all the red tape and contractors and our seller kept threatening to back out of the deal and demanding extra money every time it delayed but we eventually did close and it was worth it. 

I would assume you spent extra money on this mirror so you could attract and keep a quality tennant and would hate to loose out and have to pay to have a vaccancy and find a new tennant.  

I would imagine that in your part of New Jersey, the extra income would be significant (maybe 12k per year?).

Personally, spending the extra money on a home warranty for rentals is a waste of money.

Simply tell him or her the truth, if you don’t get expenses down you will have to terminate them and self manage or sell.Utilize utility bill back.  

Do I care about the extra interest that will not accumulate or do I care less because I can acquire another property and someone else is paying the interest?
