I think you'd have to evaluate your own situation and make that determination. 

Pick the best of the horrible applications. 2month vacancies are not acceptable. 

I will pick up my 19th in a few days.

I've been here a year and it's been great, my neighbors are awesome, and I picked a quiet street.

That will determine the next step.

I pick a geothermal as opposed to the mini-split Charlie mentioned because you would not need to augment the system with oil or gas since they have the power to heat at sub zero temperatures. 

Brandon analyze that deal in Corpus Christi and determined it was a good deal.

how is it determined?

@Hattie Dizmond@Marian SmithThere are appraisals that determine ARV value. 

What you need to do is look at the neighborhood you're in and determine what improvements are going to have the biggest impact on the appraisal value of your house.
