You have to have reserve funds for that emergency water heater, HVAC or roof problem that pops up the day after you buy/lease option the property.

They asked for a new roof, furnace be cleaned and certified, water heater repaired, new basement window, blah blah blah.

If you have a master-meter, you own the water/sewer lines and will have periodic maintenance.  

Otherwise they've got a pool of 837 to maybe find some that work.  

Stumbling upon BiggerPockets when I was about 18 felt like trying to drink water from a fire hydrant of real estate information!

Pay for a Prelim Title Report - - this is what the bank and title company would be looking at.If a few hundred dollars keeps you dry on the docks, it's better than falling into the water filled with sharks.

In Lufkin a dealer has this ad up for a New MH for $40K , delivered (but not set up)http://nacogdoches.craigslist.org/reb/5405774303.h...In my area a new Single Wide set up is running over $50K.If the Mobile's are less than 10 years old, you might not have that many problems.  8-12 years are when Water Heaters start to fail, and MH Water Heaters can cost more than regular ones.  

I am here to pay it forward so reach out if there is some info or maybe connections you may be looking for that may move you along faster.My first property I bought was 10 acres with power and no water, bought it for 30k sold it for 50k, I was hooked after that, just kept repeating the process. had a good mentor at the beginning.Good luck here hope to see you around!

In 18yrs, I've NEVER had an issue with elect, gas or water meters!!!

Some of that sounds more like ventilation and water issues (fungus) than foundation issues.
