I'm an earl-30's family guy, financially stable and fully employed as an engineer here in town.

They are a good source of repair cost information as well as stuctural engineers.

I am currently a fifth year (5/5) Mechanical Engineering student at Drexel University in Philadelphia, PA, I have recently accepted a full time job offer as a Mechanical Engineer at a chemical company located in Deer Park, TX with a start date in July 2019. 

Just the design phase, drawings,engineering, permits, etc is going to be 10-20k depending on the scope.

Hello BP, My name is Greg and I'm a 30 year old electrical/software engineer from Erie, Pennsylvania just starting out on the real estate/FI journey. 

This hit us hard but we do not want to have to deal with legal fees and more time if we had to file a larger amount, higher a lawyer, file with a different court vs Small Claims.So part of the reason why the difference is so large is because 1) we were hoping we could have a contractor come and just sand, fill, and refinish the areas that were damaged but due to the floors being engineered wood and also having a certain character to them, we can't have them sanded or you would be able to see exactly the areas that were sanded. 

Typically, plans stamped by an engineer or architect are required.

As a 24 year old working in Sacramento after studying engineering at the University of California Berkeley, I stayed for $550/mo in Rancho Cordova, all included in a furnished room in a 30-something lady’s twin house (shared a wall with another owners house).

May be best to go with an engineer or architect or contractor to get their opinion on the amount of work that is needed. 

I've had a structural engineer look it over and it looks like the main beam may need to be replaced as well as a large number of joists.
