How does one select a market?

If we send out multiple offer letters and a few of the buyers approve, can we select the best deal and turn down the others without creating an issue or attaching bad will to our name?

There are people looking to rent all year, but you may just have a smaller selection of people to choose from.

We had previously agreed on a no-travel ban for me the 4 weeks prior to the date, which meant 6 days after learning of the lease end, I'd be spending the weekend in MN, with a new tenant selected.

Just make sure that when you select a secondary market rental demand is adequate- look at rent history on properties listed, talk to PM's, sellers, local investors, etc...

As I wait for my third party to complete the screenings, I am thinking ahead to how I will make my selection.

Mine is Co-Ed, they usually come to me as a self selected group.

They offer both 20 and 15 year terms of which we have selected 15 although I understand your point about moving to 30 but we have been unable to source someone who is willing to do 30 year terms.

The "real estate guys podcast" just did an episode on market selection, i'd listen to that. 

High rent to lower acquisition point is a huge factor, but please don't ignore all the other factors - net migration, income growth, path of progress, job diversity, legislation, taxes, personnel in the area to build a successful team....etcI heard on a podcast the other day that your internal team is like your golf swing and the area you choose is the golf club you select.
