If she's renting the lot, shouldn't the owner of the lot be responsible for seer line repairs?

I also can take out a home equity line of credit on my current home....but I need direction. 

It's a pleasure to meet you, Andy.. are you considering venturing beyond single-family homes down the line?

You gave great info on background to help understand where you're at! 

It’s subtle but constant, and I can’t seem to tune it out.I’m exploring every possible way to mitigate the sound, but the reality is that I can’t change the home’s proximity or line of sight to the roads.

You can offer a 40% discount on midweek stays.

Wait, I get it, their online reputation will be enough of a guarantee for you!

My understanding is Heloc since its a line of credit can be drawn anytime so say you buy the property with and the ac goes on a heloc you could use that to pay for it where the home equity has a period/ gives all the cash upfront.

Another student rental that has a mortage of 900k me and my wife live here on a private floor. thrid property is also another rental ( duplex w a mortage of 390k ) was fully rented but tenant upstairs has moved out a year ago so I decided to renovated to do short term rental added in 2 ensuite rooms.

I don't see a reason to remove the new supports in the crawl space in the future and based on your picture, I don't think you would need to remove them to put in new floors.
