Buying a Property in San Antonio - Zoning Issue

[Ian Donovan]

Hello,

My name is Ian Donovan and I am a beginning investor looking to purchase my first investment property in San Antonio, TX. I found a great multifamily property that gets the numbers I was looking for in terms of income/expenses - however, the multifamily property is currently zoned as R-5. Looking this up, I found that this zoning is indicative of single family dwelling. Since I've already made an offer on the home, do I need to buy the home first and then change the zoning or is this something I ask the seller to do? Is it even necessary to change the zoning? Thanks in advance for any and all help!
