We had to replace a sill plate and several beams (some we were able to just sister). 

They added a support beam improperly and the cost of repairing the beam and all of the trusses and support in the attic will cost upwards of $100k.

I used AFS in the past for waterproofing and structural support to a few beams in a Birmingham home.

Is this pier and beam or concrete.

At only 3.5% down, you should have laser focus on getting to 20% equity asap so you can get rid of your PMI- it's a waste of resources and will harm your DTI. 

Remove existing carport and rear patio overhang, replace damaged framing due to termites, open up kitchen with recessed beam, new roof, all new plumbing, electrical, and HVAC, new windows, new flooring, new cabinets/countertops, new tile, paint, new sod at front yard.

I really like the beam that you used to open up the kitchen.

This wasn't quite as hard as it sounds as I had access to some equipment big enough to do it and some major beams in the building were in about the right places to make it easy(ier).   

If the severity of the situation was something like a home has been missing a few support beams and you can see the place starting to sink while the property is sitting on a small hill..yeah for sure I'd RUN! 

(Theres a log holding up the foundation beam in the basement.
