Advise on investment

[Ananth Subramanian]

Hello, I have chosen a house in Mesquite, TX. This is a 1796 sqft, 4 bed, 2 baths and 1986 built. The house looks good from an inspection perspective and it satisfies what I wanted from a house.  The house had previously a garage but it got converted to a bed room and an adjoining office room and also it satisfies all city requirements. The house is priced at 280K. 
There are a couple of things where I need someone's advice whether I am making the right decision and also the house is worth its price.

1. My question is, should I be going for this investement property that does not have a garage

2. Also the house does not have an underground sprinkler system.

Thanks,
