Thought I could've gotten a bit more but needed the property rented. 1 thing to note that I learned is we shouldn't have cut costs on tub replacement, Should've just bit the bullet.

You can also try replacing the gaskets if the unit is less than 2-3 years old.

My name is Brian - I'm a 27yo engineer working remotely and currently living in Philadelphia.

Many times the furniture will be good enough to get you started, but you may want to replace/update old furnishings to stay competitive. 

So I was initially going to sell my house but the buyer backed out due to roof needing replaced and didn't want to negotiate... that being said I am thinking about refinancing it instead to lower the payment and get rid of PMI so I can cash flow the property and hold onto it.

I'd get my money out and replace it with a conventional loan, and cash out the owner as fast as possible if you decide to hold. 

I just replaced a heat pump where the duct was already run and it took about 7 hours. 

I've seen the bad side (although that was 2010-12 or so, so I am old and biased) when inspections was a PITA and at least once cost me more in collective 'inspections fees' than the water tank replacement. 

Debating whether it would be worth it to replace the 4 car driveway for a duplex I'm getting a cash out refi on soon.

My plan is to focus on cash flow since the plan is to replace my W2 and Texas r/e taxes are high so tough on the cash flow but amazing on equity.
