Small apartment unit in Houston, TX

[Hiren Patani]

Hi,

I'm planning to built a small (around 10 units) apartment complex inside 610 loop of Houston, TX. Strategy is built it, rent it and in future either sell whole unit to another investor or sell individual units. My questions is:

1) How much land do I need to buy? ( 10 units consist of 2-3 studio units, 5 1bedroom units and 2-3 2 bedroom units). 

2) Planning to built 2 stories with 1st level unit's to have some good elevation (lesson learn hard way after hurricane HARVEY) from the street?

3) How much parking to provide?

4) Not planning to have leasing office on-site, will be using on-line website and other tools to get leasing done?

5) Property will be manage by third party (since I'm expecting lease maintenance call for first few years) property management company?

6) What other things do I need to take care of?

7) What should be my price per door to built these apartment units?

8) What should be cash-on-cash return?

9) Any Permitting issues?

Please share your experiences (good/bad/ugly). Hurdles faced by you?

Thanks for looking for post and your reply.
