The 50% rule is a guideline to evaluate a deal relatively quickly to see if it will cash flow.It states that 45-50% of gross rents will "eaten up" by expenses.

Legos, Lincoln logs, or 2 by 4s it all amazed me.

I believe we have up to a decade of low interest rate environment before I have to re-evaluate my thesis.

This requires slightly more math and evaluation than what the rules teach us.  

Anyone have ideas on how you would evaluate note funds, groups, or other means of investing in notes? 

I have been browsing the Forums a little and was looking for some metrics to evaluate and even (to some extent) attempt to predict how a real estate market is doing on a general basis.

There was no reason for Erin to post additional financial details or the property address, as he/she was not asking for help evaluating the deal, establishing an ARV or doing any of the other things that would make that level of detail necessary.  

Also You will want to collect everything you can before close - tenant communication logs past applications maintenance histories.

Several lenders will even evaluate deals with you before you make an offer.

I can also run an audit log to see exactly what was done by any employee, accountant, or anyone else to whom I've given any degree of access so that I can see exactly what changes were made and by whom.
