I find that some are more comfortable with this than typing it into a "web-based" form.

Stay off the web when looking for money.

We generally convert our data to a series of indices or percentile rankings relative to the MSA we are analyzing (or to the country as a whole if we are looking more broadly for promising markets) so we can identify which markets and submarkets are most compelling on a relative basis.We've found that the following market variables (at census tract level granularity) are most able to explain investment potential:- Crime index- Education index- Unemployment rate- Cost of Living index- Household Income- Median Age- Population Density- Median Home Value- Educational Attainment- Percent Owners vs Renters- Percent Workers vs Residents- WalkScore- TransitScore- Sound Level (noise pollution)- 1,3 and 5 year Rent Growth- Derivative of 1,3 and 5 year Rent Growth- Monthly Rent Volatility- Distribution of unit sizes in the market- Percentage of 0,1,2,3,4 beds in the market- Skewness of Household income- Number of Negative Externalities (e.g. garbage dump, firestation, prison, train tracks, highway) - We typically use this more for comparison of properties within a few blocks in the same submarket, but if there are a ton of them it is influential at the submarket levelHopefully this helps.

For security run 90 degree to external road, so people can see down aisles as they pass.Start small and Make Your Big Mistakes Early.

We are looking into building or buying a web scraper for the county property appraiser website.

Craigslist is  cesspool of scams.If you use property management software like TenantCloud (free to Landlord) it will market your rentals to a bunch of web sites with the click of a button. 

Is it strictly about the numbers or do you weigh external factors more heavily?

They said that if an external entry to the basement already existed in an R1 house I'm looking to buy, that shouldn't be a problem.3.

On the external side, it is labeled a "kickback" and unethical. 

@Rachel Mazzanti:Its not about "showing" externally that an entity is a holding company.
