From what I understand a very good deal in a great location could multiply your returns compared to a less desirable location... just my opinion... 

Rents will go up and your biggest mistake was to buy a nice house in a desirable neighborhood.The real threat is buying in the hood, leveraged up to the gills, maybe even with hard money, tenants are bleeding you dry, while you are writing checks to attorneys and contractors.Milwaukee is getting a lot of attention lately: cash flow is still better than most places and appreciation is stable at 5-8%.

If either of these numbers is inaccurate, there’s the potential to operate on less-than-desirable margins.

This scarcity has driven residential land prices in desirable areas to $1M per acre or more.

Hi Chris,We've got a couple of units in upstate New York that are located in less desirable neighborhoods that have high cap rates.

A-Class neighborhoods are high-end, desirable, with low vacancy rates.

Sure, it will take a few days but worth its weight in gold. 

Remove the desire to be right.Be able to question your opinions and verify them using actual data, not ego, or the desire to be right.

A travel nurse or relo'ing resident, student/intern can't rent from you if your calendar has a night or two locked up in the middle of their desired stay.
