No idea what you paid for this place but it sounds like you're pulling at least 1% (1200x3 rent) guessing based on the size of the mortgage.

So the biggest challenge I see with this property is the lot size.

If you aren't using a PM then it will depend how you screen the tenant and what programs you use on cost for advertising or screening( screening can usually be put on the tenant).When having the tenant any repairs that come up will be additional cost (largely dependent on the property and tenant).

Im not sure how a 53 unit complex would be depending on size but sounds big to me.  

When you say “Big” money deals, what size are you referring to?  

Even in the cheapest markets where we operate a portfolio of that size is going to run an investor somewhere in the $1M to $4M range.

Finding roommates took a decent amount of time and effort to interview and screen.

They can manage your whole PM lifecycle from website, prospect applications, screening, leases, maintenance, electronic rent collection, and all accounting.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

I’ve not used their tenant screening.
