I currently live in a 3-bedroom, 3-bath townhome about half a mile from Texas A&M's campus, which I plan to rent out once I move into the new home.

We just discovered a crack in the concrete slab foundation that is a borderline major problem:- It is a vertical crack about 1/8 inch wide that is at least 9ft long, which is causing a 3/4 inch drop in the flooring and some evidence of old (luckily) limited moisture and termite intrusion. - BUT, it also appears old and probably a symptom of the original house settling.

It is a big reason my last purchases were Dec 2021 when the rates were less than half of the current rates (I purchased $4m that month that I have already made ~$1m from).  

You mean the inflation that's already here and downplayed by half the country?

I don't see how you can force the other tenant to pay half for the service call. 

REPS requires you to spend over 750 hours annually and more than half of your working time on real estate activities.

If one moves out and you get half of the rent, reject the payment.

You’ll make most of your cash flow from half of May through Aug, lower in Sept, med/strong Oct.

A smaller SFR I purchased a year and a half ago took about 12 months to stabilize.

Probably less than half.
