I would search the BP forums because your tax / legal related questions likely have already been asked.However, it doesn't hurt to still ask the forum what your questions are.

Your actual property taxes alone on that will be over $10K a year in 2025 and don't forget about that supplement tax headed your way.I would suggest keeping the others and maybe changing to LTR if that will give you consistent cash flows.  

If you need financial help, ask under the "Finance, Tax, and Legal" forum.

No matter the number of units, there is one roof, one property tax bill, one sewer line, one gardener bill, etc. 3.

Positives are proximity, low property taxes, no income taxes, no weather events, very low maintenance stucco/tile structures, “young” properties (5-20 years old)

Congratulations, you get to share your partners tax burden and pay the depreciation recapture at ordinary income rates. 

In 2025 the bonus depreciation rate is 40%.This means that if you bought a property for $1M in 2025, did a cost seg study and found $300K in eligible assets that you could depreciate, you could take 40% of that $300K as bonus depreciation to offset your income in the first year.40% of $300K = $120K.You then apply that $120K to the owner’s personal tax rate to find the final amount that they can defer in year 1.If your tax rate is 37%, you can defer $66.6K.This is a big deal even at the 40% bonus depreciation rate this year.
