I purchased my first property (3-family in the Merrimack Valley in Massachusetts) around 6 months ago, and am currently living in one of the units and gaining experience as a landlord while renting out the other two.

Also, I expect to have some additional unpaid utility bills that I have to cover (the city of Toledo OH is extremely landlord unfriendly), like I had to do when the previous tenant moved out. 

Found out her and her brother were tired of being the landlord, only property they had, and wanted to sell.

For me, I hate being a landlord, and I can never make the numbers work on buy and hold. 

Can I legally list her as a landlord on the lease as well or no?

Could also ask existing landlord to provide vacant unit/building so that you do not incur a possible eviction. 

I am a Baltimore County, MD Landlord that specializes in Section 8 rentals, and facing a problem with filling a vacancy since November 2018 and now is Jan 6 2019.

My wife and I are going to BRRRR this property but the mortgage lender is saying that since im a first time landlord there are more strict rules with financing.

I want to stay smart and objective and avoid ending up like everyone else in $500k houses with 30 yr loans but of course there are risks to what we're doing (and headaches with landlording).

The only thing I'd caution is you will most likely get stationed elsewhere at some point, so do your homework early on a great property manager who will take the property over.There's even products for the VA that will fund the rehab of a building, so you can force appreciation and sell it for a gain (or break even), in case you decide being a landlord isn't forceGood luck!
