@Kyle CarterFor PM, ask how many rental properties they currently manage, what types of properties they specialize in, and their process for screening tenants and handling maintenance issues.

Our logical process:1) Use Neighborhood rankings to narrow down area of city you want to invest in2) Focus on getting to know that Neighborhood(s), so you know the good & bad streets, block-by-block.3) Be patient to acquire properties on good streets that meet your buying criteria.Our rankings are done with a "bell curve" approach.

It's an awesome way to jump into RE yes its scary at first but as long as you have a criteria going in it eases some of the emotions during the process my biggest thing was lower my cost or keeping it the same.

Determined to avoid such mistakes in the future, I earned my real estate license to better understand the buying and selling process.

If someone wants to be in that "it depends" grey area and try to introduce Bitcoin into a traditional mortgage application process (but don't bother trying if it's FHA), please have a Plan B and be careful with your contingencies. 

I’m in the process of managing 18 units and have a full-time job.

Quote from @Cynthia Lee: Accepting even $1 could be seen as evidence of a payment plan, and the entire eviction process could be derailed.Once you start the eviction process, to not accept any payment unless it is a full payment in certified funds (cash, money order, cashiers check).

I just bought a house that I could afford, did what I could to create equity and tried to repeat that process when I had an opportunity.

There is nothing inherently different about the process of working with Section 8 between SFH, small or large multifamily. 

It can be a long process if you don't narrow it down.
