Finance of America offers a line of credit for flipping that is based on a multiplier (5x I believe) of retirement and savings.

I am not planning to buy a 100 homes a year, just to methodically buy (cash) and sell houses using equity and my savings.     

The difference in your bank account balance between paying a property manager 11.67% (10% of gross rents plus 20% lease fee) and managing the property yourself when buying one 20% down rental property (in Northern Colorado) over 40 years is:If you invest the difference in the stock market and could get 8%, the difference becomes:If you're saving for a second purchase, it delays when you can buy that second property which further compounds the effect of property management fees on your overall net worth.And doing the full Nomad investing model, it is pretty significant differences.I am going to write a whole book about the impact on various investing scenarios.

This really did save me a ton of time.

I also am in the process of finishing up my RE license courses as I really want to expand my network, save on fees, and maybe sell some homes here and there.I've been keeping an eye out on properties within the Riverside areas around Riverside Community College, Cal Baptist University, and University of Riverside (UCR).

Also, many of them require 100k, which is more than I'd want to put into one fund at this point (only 27, so though I make a good income, not enough savings to have 100k in multiple ventures). 

.$7,000 maintenance last year $5,000 of it from a roof repair.I think for this complex I will need to put down 35%, which I have saved up, but it's pretty much everything I have saved up.If I put in a 5% vacancy, and $3000 annual maintenance.

This includes PAR and NAR fees. you may be able to find a board/broker that does not require PAR/NAR which could save about $300/year but would limit your other benefits.

It's both sad and pathetic to see so many people who have 30k in non-tax deductible Credit Card debt eating them alive and can't show 10k in some sort of savings! 

If they are backing out, which is their right, the only way to possibly save the deal would be for you to try and go back to the original agreement.
