I don't really know much about trailer parks, or self storage, but I'm pretty good at analysis, sometimes at algrebra too.
BTW, you're going to have to get some numbers from the guy, don't worry, he'll lie, but all the numbers can be verified.
Here's what my simple analysis come up with;
13A (spot rentals) + 13B (owned homes) + 53C (storage units = $130,000
13 X ($250/month X 12) = $39,000
13 X ($500/month X 12) = $78,000
56 X ($20/month X 12) = $13,440
Gross rents + $130,400
You have to find out what the MARKET RENT for a space is, what the MARKET RENT for a rented trailer is, and what the MARKET RENT for a storage unit is.
Then find out how close he is to market, and how FULL HE IS, and how full he says he is. Expenses can be verified by contacting all appropriate agencies.
How full does the place look?
How NICE does it look?
Does it show " pride of ownership" , on the rented units and the rented spaces.
Depending on how much of your own maintenance you want to do yourself, versus what he's paying you should be able to come pretty close to what the REAL NUMBERS are.
How much does he want for it?
You have to look at how much FREE CASH it throws off if you do NOTHING yourself, and how much of your time you'll have to put in, equipment to buy (snowplow maybe) if you're going to do it yourself.
My general impression when I look at deals like this (I last looked at a park in '83, but I've come close on some 4 plex-8 plex deals) is that the guy selling OVERPAID and is trying to bail himself out at your expense. If he's got enough equity though it can work.
Remember though, you may just be buying a MINIMUM WAGE (or less) job for yourself. However, if every space, is underpriced by $20/month, every trailer underpriced by $50/month and every storage unit underpriced by $5/month, you could easily jump the gross income by (13 X $29 = $260) plus (13 X $50 = $650) plus (56 X $5 = $280) $1190/month or $14,280/year!
That's a nice increase in the gross revenue, but he doesn't have to be a lot underpriced to be that far off. Again, my big thing is that a lot of times you're just buying a (not very well paying) job!
