I have seen how well they have helped him in life and want to take my own investing to the next level by buying larger multifamily projects.  

Are any lenders in Denver/Boulder doing long term loans these days collateralized with liquid assets?

I think my greatest achievement was surviving the real estate Great Depression without losing any of my investor's money (although I lost a heck of a lot of my own), without losing any property, and came out the other side with a much larger and stronger real estate investment business than I ever would have imagined.I think my "proudest achievement" is having raised over $25 million from investors (and growing), all by word-of-mouth and referrals.

This means either you define the property or the circumstances.If you define too loosely, you'll get a larger list but that may be more than you can reasonably work to start. 

Build your portfolio, experience and liquidity and credit score becomes ALMOST insignificant. 

By the way, my experience with realtors is with larger multi-family properties often going through foreclosure.  

The deals are there, just hard to find.For rentals, I also target larger units, 3 or 4 bedrooms so that I have less overhead.  

People do invest as private investors in larger llc offerings using their ira, so certainly the llc itself does not need to be within the ira, but the shares you own do.

They tend to have larger spaces and not premium locations.If it's single tenant net lease absolute triple net then yes the tenant would absorb all costs and the lease rent is the NOI.

Property values are increasing and I can use the appreciated value of my Tampa rental for a larger down payment for a larger multifamily apartment with higher cash flow.
