For instance, all the floor beams are 12 inches apart instead of 18 inches, which means even though it's a 30-year old house, there are no squeaks in the floor.

Granted it's not formally approved yet, but the code has provisions for the change of use given the age of the structure (over 50-years old) - it's grandfathered in.  

My lender showed up to my closing to support me ... old school style LOL Mr.

I’m 28 years old and work a modest job with a mid level income.

We had been "househacking" or renting our old condos before that. 12 months ago, we paid cash for our current rental (because we couldn't get a loan as a result of a recent short sale). 

I’m 26 years old and I’ve purchased two properties in the Florida panhandle which both I can cash flow on monthly if rented.

I prefer the power of my old corded Milwaukee Circular, and some of the rest is equally redundant.

I was born and raised for about 10 years just outside of Charm City. 

I don't disagree but reality is you may have bought a 3500 square foot, 100+ year old brick duplex in crime ridden part of town for $30,000 that would have a reconstruction cost estimate of $390,000 to $450,000. 

The gas furnace and AC are very old and defunct.
