I too am in Houston. I moved here to buy real estate back in 2008 but started buying here in 2006. As someone originally from CA I feel like we are in similar market with everyone jumping into Real Estate and everyone optimistic about the market.
Patience, knowing what you want and knowing what you expect will help reduce the shiny syndrome. If you have criteria that you only want 3/2 in suburban area like Katy but you get a wholesaler telling you he got a deal of a lifetime in Humble you can just pass because that doesn't fit your criteria. Staying focused will allow you to look at deals and make decisions faster.
I think the idea that you pay more and hope next year or 5 years prices will be higher and rents will be higher is foolish. So many of my friends in CA had that mindset. They will overpay because the property had multiple offers but its okay because it will be worth more next year was their mindset. Some did really well while others got on the gravy train at end of the market cycle. That game is great when it's in your favor but someone will be left holding the ball.
Everyone is chasing properties that need little to no elbow grease and expect to make $500 per month in positive cashflow. This old game of finding deals and turning into rentals is harder to come by. But as you pointed out, insurance, property taxes getting reassessed faster than in the past and finding good trades is becoming harder. These things can eat up your cashflow if you are not running all your numbers and using emotion to buy.
What you are doing is great. Staying focused and know what you want will help you stay in this game a lot longer than the buyer who is banking on appreciation and rent increase while making $100 per month positive cashflow.
I will pay the amount that I feel the property is worth. If it becomes a multiple offer situation I would use other strategies, like all cash, quick close etc to get the deal not going over my limit on what I would pay for the deal just to get the deal.
I have found all my deals on HAR.com and have not needed wholesaler to get me a deal. But I spend 2-5 hrs a day looking in between meetings, bathroom breaks etc.
If you need an agent that will not complain PM me and I can get you in touch with my son who is a realtor and makes offers on my behalf all the time with no issues.
Best of luck
