Restaurants tend to go out also due to poor location, inexperienced operator, bad food quality, bad service, prices too high for the demographic base, restaurant type for the area over saturated with local competition due to constant couponing to drive sales.

What I have found talking with other investors is that the waterbury and hartford units they have typically require more work because of the demographics. 

SEction 8 in the mid west or deep south is nothing like Section 8 on the west coast.Section 8 tenants are sought after in those markets because of the govmit paying the rent. free market rent in those areas is very much hit and miss. so they go for the govmit surety at least for the 1 year period.on the West coast there is really not much need for section 8 in the free market like there is in those markets... and its tough to get landlords to accept them.. very tough. ergo they have a liason.I mean in our markets here on the west coast you get market rent and on time generally if you screening well and you don't get the wear and tear that the average section 8 home gets because of the family demographics usually.... unless you get elderly section 8 I had a bunch of those in Vancouver wa.. they were a dream.. even though it was below market rent they never caused any issues and lived there until they passed....

You need to beware that at least 2/3s of people who say they want to invest with you won't actually invest when you have a deal in hand, so you need to have 3x the commitments you need to close the deal.Since you need to be working with rich people, you need to hang out where the rich people are.You will also need to get good at putting together good marketing materials for your deals, including your financial analysis, an overview of the market, demographics, pictures, maps, etc.  

Maybe each website have their own niche based on demographics and location/area.

First thing to understand is demographics and trends.

Baby boomers are aging so they are going to start putting homes on the market in supply plus go to assisted and nursing homes.The younger generation is often renting and not choosing to buy and reports say they don't have money saved.The housing and college loan bubble ad to this huge demographic shift.

Look at your demographics and see what you can add.  

Also I'd focus on demographics.

For example few have good foreclosure records, almost none have equity, and I have yet to see any with demographics (age, kids, etc).
