DHS has one of the lowest median incomes in the larger So Cal area, consequently it has some of the lowest RE prices. 

I am just wondering if any of you have experience with trailer homes and what your input would be (even if you dont have experience) thank you all so much.I should also say that each of these lots are zoned commercially and in this area a new north south highway is being constructed to link nothern communities to the larger metro area.

HML - 90% downpayment, 13.75% 6 month payback period, interest only Personal loan - 13.875% no money down, paying interest and principal.On a 30k rehab loan with 7 year term, I'd pay $555/mo ($355 in principal pay down and $200 in interest). 30k increase in my HML would result in $343 increase in monthly payment So the choice is: Pay down personal loan, lose more money out of pocket till refinance, smaller DP on HML VS lose less money, larger DP, and having to pay full amount later. 

I have a construction back ground, I don’t have time for big renovation projects, but would like the buildings to be located somewhere I could visit semi easily yearly and lay eyes on my investment.

Got him to accept an owner hold (@18%) that out-lived him, but once renovated I immediately refinanced it. 2 years ago we turned down $495K & earlier this year the much smaller untouched 1940's 2 bedroom bungalow next door went for $499K!!!

Assuming a couple months to renovate, I would be ok with $20k profit.

I'd like to find local contractor to renovate/rehab the bathrooms and kitchens.

@Matt Zirpoli unless those renters want the 4th bedroom I would wait until they leave before doing renovations. 

Would you recoup the price of renovation if it is a flip?

With a larger amount of mods you may realize some economies of scale where you will see a cost savings.
