On another interesting note, there are some pretty good sized companies that I have come to understand do a QCD as a function of modifying the mortgage (or trial mod).

As a realtor, I subscribed to Get Smart Charts Pro.

I thought it might be nice to have a "universal one size fits all" greeting card we can send to tenants.

I think pulling everything together into one website would be useful in my mind... but I don't know how feasible this might be...One site which consolidates MLS listings (redfin.com, zillow.com), demographic data like distribution of family size, rental unit composition (city-data.com) rental comps for closed leases (rent-ometer.com, zillow.com), on-market rentals nearby (CL), walkscore/bikescore/transitscore (walkscore.com), etc...Of course, right now, these all have their proprietary models.. maybe you can just throw them a few pennies to aggregate it, or justify that the aggregated information is your own product..

It's for an out side remodel 40 units 3 sizes so.

For example, I pay $2,500 for 1/3 of 1 medium sized zip code (so that one average zip code is generating around $7,500/year).Therefore, if Realtors go away, they lose almost all of their revenue and their free access to highly accurate listing data.Will their be disruption over the next 10 years - absolutely.

You can pick any size that is slightly smaller and trim out the rest with wood, trim and siding or aluminum.

Average rents for similar size are $1400-$1500, there are a lot of odd balls asking for $2500 for some reason, but I think those are mostly for seasonal tenants and the houses are furnished...

Check out citydata.com to see the distribution of household sizes and unit sizes (bedrooms, etc) in Dublin.

Add some more to the sold price for the 2nd bathroom (5k) and the lack of a basement (10k).There's your estimate.There are some other items too that you need to account for - bedroom count, bathroom, lot size, garage, etc.But its a pretty good start to being able to hit your appraisal numbers.
