Can you do keep going with the rent concessions instead of decreasing the rents? 

As a result, market rents increased by 4% to 6% annually in 2021 and 2022, and the overall market vacancy rate decreased to 5%.Texas continues to experience robust residential growth, particularly in the Houston and Dallas metros.

For flips, it gets added to the basis of the property and decreases your taxable profit when sold. 

Might not make much difference in rent amount but might decrease vacancy as it will likely rent faster thus equating into $$.

The equity in those doesn't mean much unless it's in your pocket OR if the market rents are slated to continue to increase; which sadly for the bigger part of 2023 rents have been flat or decreasing. 

There is still a lot of demand for deals since the inventory is very limited, but the number of buyers has certainly decreased.

At the end of 2022, price decreases wiped out most gains.

And a notion of any note worth fed rate decreases any time soon are a mirage.

Treasuries and HYSA are paying well now, but if and when the FED starts reducing rates this will decrease the yield on those investments while simultaneously increasing property values (low rates = increased demand = increased prices). 

That way you can purchase a 5+ unit below market value that needs improvements and you can apply the knowledge and experience from flipping and can see very strong returns by making improvements to commercial property and increasing rents and decreasing costs as commercial properties are valued by their Net Operating Income.
