Analysis for SFR with mother in law suite for rental

[Atta Bari]

Hi,

Looking into a potential deal in white settlement, TX which has good cash flow and has two properties on the lot. Zoning is done as SFR and another unit at the backend is as a mother in law suite. Both units are set up as 3/2, but the mother in law suite is smaller than the main unit and has been rented previously for 900 and 1250 for the main unit. Utilities used to be split by the tenants and used to be on owner name.

All aspects look good to consider it as first investment property except mother in law suite. Concerned about if there is anything I need to aware which could potentially kill the cash flow. i.e hard to rent out the mother in law unit/main unit, utility distribution, hard to sell the property, etc, or anything that you guys think I should be aware of!

Thanks in advance,
