Trailor park success to be or not to be?

Well all I’ve got to say to yaw financial blog readers out there ya hear is that my good old trailor park will be a success becomes I’m going to make it one. I’m a proud trailor park owner. Below is a picture of some of my lots of trailors I own that will generate my future retirement with the right plans to help people and help myself. (Click to enlarge picture)

I’m currently collecting enough cashflow to pay my mortgage, property manager, and all utilities.
What I feel I need to do as a landlord and real estate investor is to sell off my trailors as “home ownership” to the tenants to create long-term tenants that will fix up their own trailors over the time they own it and receive a small tax break on their taxes for interest they paid on their mortgage note. Then I’d receive longer-term tenants leasing the land the trailor is own. If they defaulted on their loan I’d foreclose on them and take back the trailor since I’m the bank.
I’d inflate the prices on the trailors I sell on my land to create low enough payments to be more affordable then they are currently renting them for to create an incentive to buy the home they are in. I’d still pay all utilities (water, gas, electricity, cable) as a full service trailor/rv park, but I would not have to pay for upgrading and repairing the trailors saving me a lot of money. I’d also be able to sell my mortgage notes at a discount to investors to earn back my initial investment of $10,000 and possibly a lot more. My goal is to buy 4 more trailors on the 4 empty lots and sell all 10 for at least $10-15k each collecting my mortgage note cashflow plus my land rent of around $200 a lot. If I could pull this task off with my property manager cooperating and on his game I should be able to pull off around a $3,500 net cashflow.

As easy as it sounds it is not in the least. I do understand great costs will be ahead. I am already redoing the flooring in a couple of trailors and some cosmetics to sell them. I’m also paying for better upkeep of the land they are on for better curb or should I say trailor appeal.
I’m hooking up a coin operated dryer and washer to increase my income. I know the tenants will use them and I’m actually considering building a mini-laundry mat on my property because its a major road and there aren’t any near by. I figure if I invested in at least 5 of each washer and dryer and charged $2.00 a load it could be worth building a small structure just for having people come, park, and wash their clothes, plus having my own tenants using them.

I took out a loan and I’m trying to use the least of it as possible. Unless buying more trailors I don’t want to invest anymore then $20,000 into the property because I want to pay back my loan before the payments are due. At the same time I need to create a master plan to make this trailor park a success in a rather small town in no-where Tennessee. There is a lot of traffic daily near my piece of land and many apartments are near it so a small laundry mat could possibly be a good idea to own. Have any thoughts?
