We have a different spreadsheet for each property.   

Biggest difference will be in pricing.

You could look into different sectors in real estate and see what you like and what you are good at; think 1.

They have different pricing... but I am wondering if someone used that for cold calling...

I will say the abatement if you do it right with a good contractor will be pricy since they have to abide by some different regulations on disposing of it. 

As you mention big difference between fraud and a bad investment.

We'll see real supply greater than real demand.Every local is different obviously, but I am talking in general.

They won't always be upfront about this with you but if know they're selling because they want to retire, that opens you up to different options vs if they're an investor just selling for profit.

Sign up for local news articles, go to events in different areas, attend neighborhood association meetings, and just go out and have fun.

When investing in high cash-flow markets, I always recommend working with an investor friendly agent so you're able to gain the right insight on the different areas and the risks involved.
