For a hypothetical example, let's say my tenants are paying $750/month for a 1 bedroom, and the market rate is $1500/month.

For example. if the payments are principle and interest and you take over, a partner who has money can help in tough times. 

Big example of why to never deal in cash...Bottom line is that you wont be able to PROVE anything...even if you file a police report, what are they going to do?

For example, if some one had a foreclosure during the 2007-2009 time period, I want to find out what happened.

For example, I have MLS access from my realtor but I am not able to see an area of my state on this MLS so I use other means to look up properties.

Example payment schedule: Initial deposit, City approval of zoning drawings, completion of Construction Documents, etc etc.Detailed deed lot descriptions can be provided via email if interested in providing a proposal.

If they won with a bid for $600K, for example, when it comes time to pay, do they just hand over the cashier's check for $400K and the court order/levy documents as payment?

For example, you can probably get a few properties with conventional financing, but by the time your looking to scale, you've hopefully built a solid reputation for yourself as an investor.This reputation will allow you to tap into things like hard money lenders (if you can do some cash out refinances on earlier properties to pay off the higher rates hard lenders expect).

My Question....Assuming the building’s conditional rating remains the same. ( Example, purchase a C+ building and it remains a C+ building)  is it....Highly Likely,Likely, Unlikely or Highly Unlikely ....that the the next appraisal for the refinance will use the same cap rate?  

For example that the loan is going to be 5% add the .5% plus 3% = 8.5% cap.
