Even though it may be little I would not use a 2x4's for the header/beam.

It is a 30 foot support beam.

If you get rid of the termites  the wood  most times  is still strong especially for a hold flip that might be a different story is it on slab or pier and  beam

My advice for new investors is to stay laser focused on developing a strong track record.

We see a lot of houses with undersized beams.

Will insurance be (materially) higher for one of the main foundation types in North Texas: slab vs. pier & beam?

To get a more accurate quote for engineering costs the perimeter grade beam of foundation needs to be exposed (soil removed) to be evaluated... this is where I'm at right now.

Sewer lines are expensive to fix, depending on if the property is pier and beam or slab it could be cheaper or more expensive.

Purchase price: $320,000 Sale price: $549,000 Complete renovation from a finished basement to installing a beam to open the first floor.

So we had an electrician doing his work plus plumbing, dumb, a GC that was really just a carpenter, and a guy doing our new load carrying beam opening up the floor plan, that was nothing more then a great wood worker and never followed the plans from the structural engineer to secure the beam properly.
