PS this is my attitude adjuster

I have seen these units work in small areas in moderate weather but can they work in cold climates in the north east?

Best to try to find comps that are very close in size, then make a small adjustment.

I would want to soak up as much information as possible and truly become a student of this business as well as someone who understands the climate of it's up's and down's.  

If the market adjusts it will delay your strategy by 5-15 years... is it still a good deal?

The biggest issue with investing in SFHs, aside from a adjustment in the market stealing your equity, is that very few SFH investors accurately estimate expenses.

A simple one page (or one line) lease addendum, or a pen and ink change initialed by all parties, adjusting the start date of the lease is all you need.

Also trying to find what best books to read on the subject and adjusting my work schedule to attend any near by REIA meetings.Really interested in learning wholesaling and then gradually moving into to rehabbing and owning rental properties.

Hopefully, that's a good sign, as market participants won't have to adjust to new rules.

In most cases with this type of appraisal, investors will pay a bit extra to have a real human being look at the results the algorithm has generated and make adjustments so that the comps would be more representative of the subject property, if possible.
