Then there will be the infrastructure that will be built to entertain and feed these new people.

. :) I think this HUGE movement of Average US investor to buy SFR rentals is not going away and is only going to keep feeding on itself and we are simply going to have to be resigned to the fact that unless you buy in areas were the cash FLOW DOES NOT work... those are the only areas that will stay predominantly owner occ and stable long term..

Buying an expensive home feeding the cash hippo and trying to bank on appreciation is a super risky business model.

I tried working a contract off a computer screen, in fact, it was hooked into a large flat screen, it was awkward with delays between feeding new pages, time for chit chat that brakes the stride of the presentation of closing the deal, it's not for me.

You can find good data on REALTOR.com as the feed is direct from the MLS.  

Problems come into play when we have a tenant who doesn't know what clean means, or that they need to call us when there is a leak, or that the garbage belongs outside and cat food in a bowl - stop feeding the mice already.

If you plan on expanding on this particular model and adding things like sensitivity analysis or any type of simulation then I'd back track a bit and create separate input screens that then feeds your actual model.

This feeds the gentrification loop.

Those of us active in the business don't bite the hand that feeds us.

I work with another agent that feeds me deals that don't fit his criteria but fits mine so now I have another pair of eyes working for me.Hope this helps.
