Personally, I’d only be comfortable doing this if I was comparing options in multiple cities.
Getting into the property investment market and selecting a city purely on the basis that the cost to entry is modest isn’t prudent.
I’m a mortgage lender and have financed lots of investors in Austin and we’d oftentimes talk about comparing Austin versus San Antonio, Houston, Dallas, etc. I think any of those have merit depending on your risk tolerance and what kind of money you have available. That said, you’re looking for data that helps quantify the markets-a title company or realtor in each could pull sales data for you and you could make projections based on historical appreciation (ignore 2020-2023, too exceptional). Texas cities, even with our ridiculous state government, have a strong record of appreciation and population growth and I’d want to use that as a baseline in comparison to whatever market you might be considering.
