I've seen extensive foundation repairs done to cinder block walls that are bowing from external hydraulic pressure, and they've been repaired with extensive steel beams, tension systems and a drain cut in for around $12,000.4" is a fair bit of slope and to put in floor leveler...well, that's a lot of floor leveler.  

Good luck @Bryan Beam!

Daymond John and other main speakers emphasized the necessity of setting clear goals and maintaining a laser-focused mindset to overcome obstacles and achieve success in the competitive world of STR.

@Jack Wang One thing I’ve been coming across recently is dry rot in the support beams in the basement of the homes.

Either their costs upfront outweigh the long term desirability of the designs (see geodesic dome houses or underground houses) or their costs are high due to the attractiveness of the designs (see post and beam or timberframe homes).

Yes, there are some people who do podcasts that are laser focused on a particular niche but based on what you said in the OP you don't seem to really have a niche yet which is why I say that by listening to the BP podcast you'll learn what other podcasts you should be listening to.  

Your grade beam is typical.

Right now I am laser focused. 

. $4500 seems like A LOT of money to transfer our digital plans into CAD (the contractor already built-out our design ideas on his laptop's software) and have an engineer ensure we're using the right beams in the right places.

@Ericka Luddy Thank you I'm keeping a laser focus on my pathway to succeed in Wholesaling.
