Hey there! San Antonio is a great market for STR! Knowing what type of property and what areas are the first steps to success.
For utilities you can call the utility company and they can give you an average cost for a specific property for the previous year.
Landscaping depends on trees/bushes/flowerbeds etc. I would say $250 on average monthly. If your property has lots of southern live oaks you need to factor in another $500-$800 every other year for tree trimming
As for scorpions, spiders, snakes etc. I’ve not had a problem with any of these in the 2 years I’ve lived here. I moved from north GA and had way more bug issues there. However I would still recommend regular pest control service which is usually around $50 monthly
I'm on the Investment Team at PMI Birdy Properties and help clients acquire properties for use as STR. My brokerage also manages over 100 STR doors in the area but you are not required to use their services if you use me as an agent.
