But there's more...how will you fund the development costs like:  engineering, municipal/impact fees, water/sewer, utility connections/septic/sewer, legal fees, soil testing, permits/fees, road construction, more. 

Solar, propane for heater & shower, mini split, fridge that runs off DC, tongue & groove ceiling with puck lights, farm house sink with butcher block counter tops, full bed with storage underneath, 3 seatbelts connected to couch that turns into 2nd full bed, all electric is stored under bench, an induction stove top, fully furnished with pots, pans, and work out essentials, and our favorite part: A ROOFTOP DECK to enjoy the sites.

Or your sewer lines may be shared underneath the home...an easement could be a possibility for a shared sewer, but it becomes more complicated if they are shared below the slab where you'd essentially need to access someone's home...Zoning: Setbacks are written for the perimeter property line.

Over time, fine particles fill the pore space in the soil. 

I'm not sure about the soil conditions in your area, but the soil type could also be an issue.For the structural repair itself, the engineer recommended a few different options: 1.

Check the grade and have a landscaper bring in heavy clay soil if necessary to build up around the foundation.After you have done these three things and you still have problems it's time to call a basement contractor and have the drain tile system looked at.

The soil is now getting tested and the utilities company is getting called.

Went and took a look at a property today that is listed as having a concrete slab foundation.The home shows all the signs of foundation issues on the exterior, and interior.Upon closer inspection, we were able to remove a loose brick at the very bottom near the "foundation".......we were able to see that the house is built on wood beams, supported by cinder blocks.The outer edge (about 6 inches in width) of the "foundation" is concrete, as if they poured concrete just to support the perimeter of the home.Question.......how would this issue be fixed with sagging beams underneath the property?

Personally, I spend significant time looking for foundation issues, significant settling or structural issues, and indicators of previous flooding (particularly flooding caused by groundwater rising up from underneath the slab)--these issues are usually deal-breakers for me.

(I also have some ignorance from living in California for all 24 years of my life, where $50,000 can't even buy you a cardboard box underneath a bridge)Knowing what you know now, what would you do with $15,000?
