In addition to the 6 apartment homes, there are three empty lots being sold with it.

@Jamie Hall  Ask the following questions to all potential brokers (in addition to commission splits, fees, etc.)  1)  Who will be my mentor, what is his/her experience in total # of MF transactions broken into buyers/sellers, how available is he/she, and what expectations (if any) will he/she have in return for advice (beyond commission split)? 

I know if we were taking out a loan this would not be possible as down payments for investment properties cannot be gifted, I'm not sure what the rules for all-cash purchases are.Since I manage our other investment properties in the area (all under my name), I don't want to put this new property in her name as it will create additional hassle of signing a new contract with our PM, creating new accounts with the utility companies, etc.Thanks in advance for the help!

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.
