@Steve Kim What I would do is check the assessments of newly sold (2019) multifamilies in your appraisal district to see what they are paying. So, for example, if there's been a couple of duplexes in the $250K-$400K range sold about 12-18 months ago, you'd want to see what they're paying now and how far off their appraisal is from what you think their market value is. A real estate agent could help with that. Or, better yet, just look at what the published city, county, and special fee rates are overall, and you can bet that if you are paying $300K, it'll be assessed at a smidge under that but pretty close. If the rates are 2.5%, for example, assume that you'll be assessed at $290K at least. Every property I've ever bought has had a property tax pop the year after I purchased it. They have no mercy on us investors! I'm almost certain you are going to be paying $7200/yr on a $300K property by next year. Maybe more.
