A tenant on a lease agreement would be my last choice because you have less flexibility since you need to honor the current lease and rental rate. 

Be friendly (kind-considerate-respectful), firm (be clear about your expectations and have the moxie to address issues as they arise), fair (comply with the law, no favoritism, appropriate response to the situation) , fast (quick to respond to maintenance requests and other tenant concerns), and flexible (when the situation warrants).

There's not much flexibility in the budget, but it seems worthwhile if the the appraiser is likely to consider it in the valuation.Thanks for any thoughts or opinions!

Keep in mind that everything can be negotiable and flexible.

Assuming you're under $1M and going the bank route, it's always best to get quotes from several different banks, and then compare them based on rate, term, amortization, and flexibility.

This gives you maximum flexibility in terms of the sale.

But they usually want a flexible check-out date, which makes it tough to plan ahead.. 

I would prefer affordable and flexible install dates (instead of 4-5 weeks out).Thanks in advance!

They tend to hold on to their mortgages, not sell them off to Fannie/Freddie, so they have a lot more flexibility.

My military training has taught me to come up with a plan, even if not perfect, and execute it with 100% intensity and be flexible enough to adjust direction and tackle problems in the moment.
