Some of the information could be sourced from the 2000 census for all I know, and is 9 years old.Also, "neighborhood" data could be vastly different and I've found when looking at their population information for instance (46,557 in this case) is not neighborhood by my definition.

Save the difference to build up a buffer.

I want to gather hard data before having The Talk with my folks.

I have a MAX OFFER column that uses the formula =SUM(B2*0.7)-G2, in which B2 is the ARV and G2 is the REPAIRS column.Any others tracking this data like this?

I don't know of a service that provides this.The NAR and local state real estate commissions track certain data but it varies by state.One state can have 2 mls's for that state and another could have one for every other county.So with broad data is basically useless as you are trying to extract data in your local marketplace.You could track how many agents in the county by the REALTOR board but it would not include non-REALTORS.You can get tracking data from your local state commission but they charge you for it.What are you trying to do with this data??

Apparently 9 of the units are currently occupied and per the seller occupancy goes up during the summer with some temp workers that come into the area.Per City data, average rents in Podunk USA are $572 (15% lower than the area I currently invest in).So if I accept $230k as fair, I would mortgage $172,500 (75% LTV) for a payment of $1,090 (6.5% for 30 years, is that reasonable for commercial?).

As someone who probably puts more about my rehabs out there than almost anyone (including pictures, budgets, detailed profit data, etc), I can attest to the fact that providing too much information to a potential home-buyer *can* be a bad thing.It's only happened a couple times, but I've had buyers who have come across my blog, have seen the before pictures and the rehab budgets and have gotten very concerned because they had no idea that *THEIR HOUSE* was ever in such poor condition -- buyers don't like to think they are living in a house that once had mold, termite damage, etc.

Today I sat down with all my data and looked up the owners.Some of the owners are corporations, LLCs or trusts. 

For automated web forms linked to a data-base I use Podio often.

We've seen a lot of technology with data and bits, but we haven't seen a lot of technology with atoms in the last 50 years.
