@Gregory Schwartz rates are above 7% now, so not a stretch to see them staying in a 6.5% to 7% range next year.

I don't do large rent increases (like $200) because I don't want a unit turn but my rent is in the market range.  

I know what the rents should be for each of the units (2 vacant and 1 significantly under market), the taxes are listed on the MLS, I’m familiar with the water/sewer costs in close proximity to this building, and I know what percentage to use for my Vacancy, CapEx, and repairs and maintenance based on my knowledge of the local market.

If so, what rent ranges are what class?

My property tax rate is 2.70% I have a great tenant so I haven't done large increases (like $150 or $200) since I don't want a unit turn but I'm in the market rate range.

Village to Village Network (https://www.vtvnetwork.org/) and Men’s Sheds Association (https://usmenssheds.org/) are successful models of people building community to improve the aging experience.So drawing on Dr Thomas and Nancy’s work and incorporating cohousing and pocket neighborhood elements into my communities, I have chosen to use shipping container homes in areas along the Texas coast where storms frequently cause wind and water damage.

Would the fact that our house is in the ~ $850k valuation range influence your advice? 

go to Home Depot, talk to some general contractors, join your local Facebook and meetup groups and start getting good ranges for every major item.
