So I’m planning to move 1,000 miles away from my hometown in approximately two years.

#3 Would the 6k with labor and materials be a more accurate estimate?

It's a good idea to get an estimate from a contractor to back up your deduction and keep everything transparent for the tenant.

Between now and then you can really crunch the numbers on rent vs. costs and decide how much negative you can stomach....at worst you still decide to sell in the spring and maybe it's a $40K loss instead of your current estimate. 

The appraised value is exactly what I estimated, as well as the market rent and expenses.

First is the Midwest, which by most estimates is the cheapest and most affordable part of the country.

From looking up on Glassdoor or Indeed I'd estimate their tech salaries to be $120,000 (on the low end) to $400,000+ (I didn't ask them their salaries, didn't want to be too nosey).

I currently own approximately 100 residential properties and a few commercial properties here. wow congrats Remington !!

If there's a repair or capital expense like new water heater, might take a little more time with getting estimates. 

I own a house with approximately $400,000 in equity, and I'm considering tapping into this equity while I search for a new job.
