Houston has historically been a strong market for garden-style apartments with value-add potential, and it continues to be a desirable location for real estate investment, particularly in the asset class and business plan you mentioned.

Historically, we built a lot in the Lakeridge area in Cedar Hill and Grand Prairie.

More landscaping can cause higher water expenses and maintenance costs, a different city can have different water, sewer, and trash hauling rates, pay scales can differ from region to region, property taxes vary widely, and so on.To sort all of that out, I use data from the property's historical costs for utilities and contract services, tax assessor data to estimate post-acquisition property taxes, and my own operational experience to estimate payroll, insurance, R&M, CapX, admin costs, marketing, etc.

We expect it to be steady for a long time simply because this area has historically been in somewhat high-demand.

I just posted this on another thread but you can go on the various cities websites and find more historical data about vacation home performance in that market.

Historically, the recession could have been better for the stock market, so finding recession-resistant investment becomes paramount.Commercial real estate, with a significant amount of debt due, may be impacted.

Housing supply, historic appreciation, and how desirable an area is(population change) are the primary things I look at to determine how much appreciation I expect. 

The historical financials for the property I'm looking at show an average annual expense of $1,250/unit.

Historically my business was  Grossing 540K this was before life change for my family How can one little place make that income you might ask. 

I currently only own a quadplex in the East End historical district but am seeking to aquire more similar properties.
