2) Does that 7% rent raise limit apply if you switch landlords?

I think it would apply. 

I helped them apply for a rental assistance program and I will probably forgive one months rent to help them out.

Applicants can apply and be screened online.

You can also apply for a FHA loan as well. 

I'm going to use an FHA loan for this purchase since I don't have enough credit to apply for a conventional loan.

I'm trying to use the Rental Property Calculator applied to the property owned, but not sure if I'm doing that right.  

Now depending on the number of times you've used the program, your specific military service in some cases, and the loan type there are funding fees for the VA loan program; if you're at 0%-4% down, it's under >4%, 5%-9% down, it's a little over 1.5%, and over 10% down under 1.5%.So if you wanted to sell the investment after time and use this as your primary & house hacking until ‘dream home’ days (or moving out of your in-laws), you could sell and pay off the original loan balance and go this route or pay off original loan amount without selling and keeping it and apply for the one time benefit restoration - which is not the same as entitlement re- installment for active/permanent change of station orders or foreclosed upon properties.

Since all grass was removed I expect sod to be placed after all debris is removed and top soil applied, trees replanted, fence installed, and sidewalk redone. 

Depending on the size and your location these number may not apply but locally to do a termite bait/spray generally in the 200/300 range for a 1,200 SQFT property.
