REI is not my main source of income and is only a very small slice of my overall portfolio.

It's fine to invest hoping for appreciation, but counting on appreciation as your sole business model is gambling with all the risk but none of the fun.If you want to keep it, I'd consider using it for a vacation rental. 

Sellers need to know, agents need to know, settlement agents need to know and lenders need to know your ability to perform and lenders need to know the source of your down payment.

I'm looking for a commercial real estate brokers who can help source B&C class multifamily properties with 25+ units in Washington DC

  - Offering a competitive interest rate on loaned capital - Having investor own the property, but split cash flows 50/50- Allowing myself (sole LLC manager; where property would be held ) to receive a quarterly % of AUM (Assets under management)Any input on alternate strategies would be greatly appreciated!

We have been using five column accounting paper for income and expenses and including the rentals from sources other than the mentioned one. 

Also, meetup.com is another great source for local REI clubs too.

If you know the answer, and if you can get a link or a source, it would be great too. 

Residential is pretty straight forward with houses so not as much broker/agent value there except for sourcing the deal.

I am not ready yet to take this step, but I do consider source of income when screening for new tenants.
