Larger operation expensesIn the ideal situation, a multifamily unit in a nice area that has a high renter population would be great.

They sound small, so it's likely that there aren't brokers focused only on them, but rather will be covered by brokers in nearby larger cities, especially since you are talking about commercial properties like hotels and multifamily, and these tend not to be handled by your local residential brokers.  

When I say this I mean that if you are restricted by capital that keeps you. below the 100k mark then you really don't have much of a choice, however if you have more liquidity that is possible to use then you could go int it with the goal to find something under the 100k mark and still be open to higher priced deals that may have other upside like appreciation and overall area development that increases the price of the home over time- (capitalizing on gains that may not be received by buying in An area that is lower entry but provides great CoC return/ cashflow only as opposed to larger appreciation in addition to okay cash flow.)

I am partnering with an investor that is looking for larger parks.

One thing you want to look for is uneven multis, meaning one small unit and one large unit so you can live in the small unit and cash flow on a larger unit.

It is very analytical and really for larger deals than what I'm looking at but may be good for you. 

I am planning to live in it for about another year afterwards and then use it as a rental after moving to a larger city for more career opportunities.

Larry, I have a few office and retail strip properties in a different state, but I'm currently paying 4% (of gross income) for buildings larger than 25k square feet and 5% for the smaller buildings.

Have good working capital and would be starting off with this (a larger one will be my primary residence ideally).

You could buy several 2-4 unit properties, or a larger multi-family.
