Mobile Homes ON Land questions

[William H.]

So here is what I am looking at: 10 MHs each on their own land, all older models that the owner is currently renting out. 9 are rented out, and 1 is junk and will need to be removed. This is a neighborhood that is mostly MHs and small SFR homes and as far as I know if I needed to bring in a home, it would be allowed. The lots all currently are set up with city sewer and water. I don't have a lot to base the lot value on because there is not many sales in the past 20 years. However, they are selling some empty lots in the neighborhood for around $7,000 each, but I would need to tap into the water and sewer. The price is currently $200,000 for the 10 MHs and land, putting them at $20,000 each. While I think that there is some value in the water and sewer already being in place. Still seems like a decent deal.

My plan is to sell all of the homes for say $2000 each, and just own the land under the homes and hopefully find good tenants to pay me "lot rent" ideally of around $300. That way I just own the land, and have a smaller headache than running around fixing these older homes. Does this seem like a good price/deal in general. My thinking is that even at $200,000 if I took that same money and bought one, or 5 SFRs I would make either the same or less money after Cap x and management. 

I am new to all of this so there are some things I don't know and maybe I can have answered: 

What does it cost roughly to run water and sewer and tap into the city (rough idea, lot size roughly 160x90)?

What are the cost to remove a home once it becomes to run down?

If the current older homes are renting from 400-800, is planning to do a lot rent of $300 a month do able (currently the tenants are paying for all of their utilities)?

If I were to buy any other lots in the same area that didn't have water and sewer, would I be better off moving a 3/2 single wide onto the lot and finding a buyer, or trying to offer a incentive for someone to move their home to my land? 

These are just a few questions that I have, but to me it seems like a better route than the other deals I have looked at. 

Let me know if anyone can answer anything and let me know what I am missing. Thanks!
