Adding my thoughts, i see few investors who want to do safe bet on getting new construction homes for rental.

A simple, low cost method...especially if it is only a problem for a few months out of the year...is window units (for heat or a/c) or baseboard heating, to help supplement the temperature provided by the HVAC.

In my opinion, if you are remote, it should be stronger cashflow, and I wouldn't bet on appreciation. 

If you have a decent W-2 to cover the loses, you may choose to bet on appreciation, but this is speculating and can bite you in the behind. 

A or B class is a different animal than a C or D.

Also, don't bet on a one month turn around for your rehab unless it's just lipstick.

I can promise you this, you might get one home run like that, but your not going to get them all that.If you are building for those numbers, I would go knock on the door of every developer and let them know, because your going to have so much business you won't know what to do.Habit builds for $75 sqft national wide average and they get deep discount on building materials and tons of free labor.Our cost are running right now at about $105 sqft and I'm in Michigan, I would think we would  be ton cheaper than New York and i know we are cheaper than Oregon, maybe I'm wrong, maybe I"m right.

They will be your best bet on a deal like this.

A, B, C or D neighborhoods??

I would rather have a few good happy buyers to pass stuff off to than have to depend on a constant stream of new idiots to overpay (granted the last few years this doesn't seem like a bad bet...) on every deal.
