That being said, with rates and prices where they are these days BRRRR is very difficult in just about every market. 

Had a similar situation, inherited a tenant from a former building owner, where the 3br rent was $550 month. 

Hello Ilya,Where are you looking at purchasing your 1st property.When converting a property from a single family to a multi family, you will need to check on the zoning requirements, depending on your location, not every location has zoning.As far as lending goes, it is far easier to finance a single family up to a quadplex, than financing 5 plus units, the DSCR Market for 5+ units is extremely low right now, and there are few if any lenders in that space.For financing 1-4 units, there are Millions of dollars chasing those loans, so you can easily obtain long term financing, at rates between 5-7%.Please reach out if you have a property identified, and I can help you with financing options.

As for where to invest?    

@Javian Moorman - Where are the properties located? 

I've got some cash saved up but no where near enough to cut it. 

I suggest you do this regardless of whether the PM is licensed or not.Pro Tip: Even in states where licenses are not required for a PM, it's always a good idea to hire one who has voluntarily obtained one.

While I only have one LLC right now, I plan to expand to multiple LLCs (one for each property).Here’s where I need your help: How should I set up my account to reflect all the real estate activities like rental income, expenses, and distributions?

I work for a Property Management company in New Jersey, where we manage various properties across the state and New York City.

Figure out your costs and buy homes where you are stationed that will be good rentals after you leave to go to your new posting.
