Another pro can be that neither accountant will likely increase the bill to you from year to year in fear that the other accountant can steal the business.

I actually did reach out to them about a couple properties they have with some identical photos asking for some clarification.

Not much money being made operating one of those finger stealing machines.

What if it takes you 45 - 60 days to evict with no rent and then the tenant steals all the appliances and trashes the place?

I found out that Quicken Loans was having a "cyber monday deal" that offered identical interest and terms as the credit union deal I was working on, but offered closing costs that were about $2k lower.  

Then one you will find available will just steal your money.

You claim chart #3, the Case Shiller 30 year, looks almost identical to chart #1.

For instance, if I was to find a good real estate deal and I convinced another investor to contribute 50% of the  funds, would I have to provide a contract to basically say I wasn't going to steal his money?

It is not a right or wrong deal rather just the differences between identical sfrs in totally different locations or the diff with classic Porshces and Civic/Pinto rentals. 

SCAMMER steals the photos, makes their own listing...typically about 1/2 the price of normal rent and with some key words that turn people on...like pets allowed, no pet deposit, maybe no deposit, just 1st month's rent....something like that to make it attractive.
