We know 3 of the units can't be the issue since they either moved in or out while this was happening. 

If you are going to move forward with this deal, you’ll want to have a review of HOA financials.  

Another option is to split the cost based on the number of occupants in each unit but this also means you'll need to adjust the charges as tenants move in/out, so it requires more work and I wouldn't recommend it.

Thanks to everything I’ve learned from the podcasts, books, and this community, my wife and I currently own:A triplex in MaineA single-family rental in San AntonioA single-family primary residence in Las Cruces, NM, which will become a rental when we move in a few monthsFor context, I’m an active-duty Army officer with about 12 years left until retirement, and my wife works for a university in Boston.

I became a realtor, what I would love to do is move to a place like Mexico but I have kids still in school. 

Tenants like to set up insurance, show proof to the Landlord, and then immediately cancel the policy after moving in.

I've been in each unit within the last week so we can rule out the portable washing machine.After hunting season (insert "you might be a redneck" joke here), I'll move one of my trail cameras into the laundry if the problem persists.  

Off-Market: I was working for a storage facility and the owner needed help removing his stuff because he was moving How did you finance this deal?

No deal is perfect, and anyone on these forums will have different investment objectives as you, but you will typically get some things to at least think about before moving forward.

@Gil CanfuBased on my experience working with over 400 investors, investing in a single-family home in Dallas with a $300K budget is a smart move due to the area's strong rental demand and appreciation potential.
