Maybe you are better off renting for now while focusing on increasing earnings, saving, and developing a plan.

However, the substantial price increases and lack of inventory have lead me to start buying tax deeds, which Georgia is a penalty state offering a 20% (non-prorated) premium. 

I think that it's so they can increase their fees charged to guests. 

There's no good "ballpark" figure, you have to know the amount of stays, cleaning fees, some add in pet fees and other things that can increase revenue.

The macroeconomics here is rapidly growing - lots of population growth and job growth especially with the many companies moving and developing out here like Intel, Honda, Amazon, Google, Meta, etc.

Go where your income to cost of living is the greatest ratio, hands down.A good portion of my borrowers buy out of state and use property management to deal with the properties.If your in college you've gotta increase your ACTIVE income, before you get passive income.

I own a rental in Ohio and would like to increase my investment (purchase another one or maybe two). 

Lease renewals have a strict deadline. if you miss the deadline and fail to request a rent increase, then you will need to wait until the following year. 

Will this cause more short-term rental owners to sell out on top of the noticeable increase we have seen this year because of the triple whammy?

I have found that making property improvements does more to increase the rental pool than lowering standards. post a picture of the kitchen.
