Submarket Research Process Help

[Chadwick Gonsalvez]

Rookie investor here; what set data points do you try to find when you're researching a submarket? I want to develop a process, but don't want to waste time with gathering research points that are ineffective. Below is the questionnaire I've come up with, although please feel free to critique it! (note: for trends/growth I'm looking post COVID due to it's impact)

1) What percentage of submarket (SM) rents vs Dallas avg?

2) Rental population trends - is % of renters growing over time?

3) SM Property Value Appreciation Trends

4) SM Pop Growth

5) Safety compared to the rest of Dallas

6) Income - median and avg

7) Rent Cost - median and avg

8) Rent Growth Trends

9) What percentage of population under poverty line

10) What percentage of pop are families 

11) What percentage of population are families w kids

12) Avg people in a household

12) historical vacancy rate

13) avg bed/bathroom composition

14) Profession by percentage 

15) Commuter population by percentage and commute time

Thanks y'all!
