New to mobile home park investing..

So I recently found a mobile home park for sale. It has about 18 units, all are not rented.  All lots do have homes on them, but not sure if they are part of the property or not.  What should I be looking for. Units are older and lot rent brings about 250 (i think). What would you be looking to find out before you buy it? Also would you buy this instead of a couple single family homes? My main exit strategy is to buy and hold for the monthly cash flow. I am hoping that this sells for close to 75k.  Numbers are rough and most likely estimates. But would love some advice please.
