Given your goals in getting into multifamily, it may be worth considering the opportunity cost of selling now & potentially losing out on any additional appreciation or whether you'd be able to find anything in the multi space anytime soon.

I currently own 50% of a 45 unit mobile home park in South Daytona and I have an additional 4 unit property under a cash contract.

In addition, if they have had the dog there for a long time they may be able to argue that the landlord lost the right to enforce the no pets clause.

These are all great suggestions, I would add do not overlook the power of referrals and building a network in addition to online marketing.

Additionally, I have a decent amount of flexibility at this job and experience large periods of downtime on a daily/weekly basis. 

Just an additional avenue. 

I've looked over many of the older posts in the MN forums so I have seen some names thrown around, but just thought I'd see if you had any additional thoughts.

We're after a multi-family unit to purchase so we can rent the other apartments.By day, I'm an AI researcher but looking to build some additional cash flow through rentals.

Any additional suggestions, advice, guidance or even cautionary tales would be greatly appreciated.

You mentioned some small rooms, this often happens when a large addition is attached to an older smaller house.
