When I was his age and even into my early 30's I had a fear of speaking to people or publicly and am comfortable doing it now, but we have felt this is a good skill to have.

The other thing to consider is the age and if you add a second floor will the entire structure need to be brought up to code for hurricane and wind.I live in a neighborhood where the homes are older (not in florida) and the foundations are hollow core CMU and adding a second floor would not be feasible due to soil bearing.

I wish I started to look into RE at that age! 

They are not able to assign a value to things like roof age.

Its extremely important when running tighter margins like what you're talking about to focus on age of HVAC, water heater, appliances, roof, etc.

Not all do, and there's potential those carriers won't accept the risk for a myriad of other underwriting reasons, too- age, current condition, etc.

Age wise that's not bad and is pretty typical for investment class assets here in Memphis.

I think their general stance is going to be to go with whichever comparable property has the greatest degree of similarity in terms of (probably, in this order): location, age built, quality of construction/current condition, and square footage.

If you borrow against the equity, you'll need to include that payment in your calculation, as well.You make 3x the average income for Pennsylvania at the age of 32.

Credit scores are a reflection of someone's ability to learning and understanding the rules of the game and haveing the discipline to play by them.If you already have good credit, already pay everything on time (autopay), then increaseing your limits will probably help you the most, because it gets your utilization down, ideally under 10%.Higher hanging fruits are average credit and account age (just have to wait for that I guess) and inquiries, which are sometimes unavoidable as real estate investors.
