I called your referral but seller canceled the contract after inspection because it has foundation issue so we ask for discount to cover foundation problems.

Now you must remember a foundational rule of REI that ownership means nothing, it's just control of the property we are after, that is what wholesaling is built upon correct?

I know I've spent a lot of time with potential investors only to learn their only investment interest was in the stock market.Having your foundation for raising capital in place prior to signing a deal may be an easy concept to grasp, but developing that foundation takes planning and hard work.

When you own or have bought numerous investment properties you soon realize that you need to look at the foundation, roof and A/C heater most everything else is not significant to worry about.  

If it is foundation issues, 10-20K for repairs is not uncommon. the good news is most foundation issues are repairable, but can get expensive.

The new home deal however would have brand new septic and well.What would yield better "forced appreciation"--forced appreciation from rehabbing the house (make money like a "flipper"), or forced appreciation from putting together a new house on a lot with new foundation, septic, well, etc...

Removed debris and overgrowth on property, new siding, windows, exterior doors, total gut of interior including removing walls and re-engineering structure to support roof trusses and ceiling joists, rebuilt staircase to accommodate new kitchen design, replaced entire block foundation wall that was heaving inward, replaced sewer drains in entire home including underground, drain tiled, and rebuilt both bathrooms and prepared current garage to be remodeled to become master bedroom and bath suite.

Im going all in now and want to build a solid foundation to grow from.

If the house needs a sump and a pump installed for the first time ever, then it's closer to reasonable, IMHO.I used Foundation Recovery Systems to install a sump pump and drains in my rental house in Independence, MO. 

Not practical....there is no foundation that deep for the existing house.
