It might not make sense to do a 1031 exchange.In PA, state income tax will be due on the gain even if you do a 1031 exchange.You will have to pay a qualified intermediary (QI) to handle the 1031 exchange; that might run in the ballpark of $1000 or so.If you already held for a year, you are now into long term capital gains tax rate rather than short term.

We tell new people all the time to try to hook-up with more experienced folks, and learn from them, and so it's strange to me to hear that frequent posters would also lack the common business courtesy of a response, even if just to say no thanks.

This is common. 

This makes sense.  

I am not sure about your area but around me it is not a common expense that a tenant would pay, so would love to know the reactions the tenants have and if you experience higher vacancies. thanks 

But the numbers definitely dont make sense if you are trying to get some cashflow.So, I settled with a B class.

Here are the key data points:Park info  Located in Alabama61 lots25 owner occupied homes18 park owned homes (14 currently rented; 4 currently being repaired and should be rented soon)18 vacant lotsAvg lot rent - $160 (unknown what the market rate is but it doesn't sound like there has been a rent increase in at least a year, maybe more)Avg POH rent - $400Expense ratio - seller claims 26% but I'm estimating 35% for the lots and 50% for the POH'sCity water - individually meteredSeptic - good condition (allegedly); a couple were pumped last year, none this year (no lagoon thank heavens)Seller claims gross income $130k, expenses $30k, and NOI $100kI calculated gross income of ~$135k, expenses of $60k (55% on POH and 35% on lot rentals), and NOI of $75kOther infoMom & pop seller, but park is listed with a brokerPark has been on the market for > 3 years (recent price reduction)Greater metro area stats look goodPopulation = 115kMedian home price = $105kUnemployment < 8%Household income > $40kHousing vacancy ~ 15%Closest Walmart is 7 miles awayFreeway is 1.5 miles awayNumbersMy valuation is coming out about $80k-$100k under the seller's asking priceWith conventional financing I'd be hoping for a purchase price of $500k, $100k down @ 6% over 20 years (not sure if this is plausible or not)Assuming that financing, I'm expecting net cash flow of $40k (after debt service)Upside potential is in raising rent and filling the 18 vacant lotsFollowing the same assumptions above, raising rent $50 (if the market supports it) would change NOI to ~$90k and net cash flow of just over $50kFilling the vacant lots could potentially increase gross rent up to somewhere between $150k-$200k, depending on what the appropriate occupancy rate is for the areaWithout verifying any of the above information (haven't offered anything yet so there's a lot of DD left to do), the deal seems to make sense. 

That would be my first choice but, correct me if I am wrong, since you know the local market here better than me, but it looks like it's pretty hard to find deals tjhat make sense with that kind of down payment.

@Joseph Chan  MTM is fairly common.

I have 2 stacked units in a 2 family student rental ( 8 beds ) on one hand i wish i did not get them because i have been having to reset the machines ( have to have someone look at that) so in that sense i wish i didn't have them because of this maintenance, but if the Students lived in a dorm they would have to pay to do laundry and the local laundry mats are twice what i charge, it's more for convenience for them. the money i do get helps pay for the gas, water and the electric that the machines use as @Dale Stevens mentioned. i do not make money on them, but helps with the cost when the rental market is so competitive for student housing where this is.
