I have seen some fluctuate from year to year based on pay increase or hours cut at work.  

I understand the basic gist which seems to be that a property is assessed every 5 years at the current market value and there is a significant homestead exemption for owner-occupied homes.However, what I am finding hard to get my head around is that the actual taxes assessed seem (at least at the few properties I've looked at) seem to fluctuate more than I'd expect.

They tend to have higher interest rates that fluctuate.

As rates push higher sellers also become disincentivized to sell because they'd be going from 2.X% or 3.X% interest up to 4.7% (or whatever rates are tomorrow, since they seem to fluctuate 20bps per day these days)Hope this helps and happy to chat further!

You'll have fluctuations year to year but over the long term you'll be gaining $50,000+ in equity / cash flow every year indefinitely.Personally, I would hold onto that property for dear life and refinance opportunistically to continue pulling out equity.

The teller shrugged his shoulders and said, "Fluctuations..."

Consider this when you are setting the rent amount. whatever you do use real properties in the area combined with rentometer estimates. zillow and relator.com estimates fluctuate by the day. 

At the same time, mortgage brokers will tell you rates can fluctuate day to day, week to week.

Variable rates typically are lower for now whereas the fixed rate is typically a higher rate but won't fluctuate as much. - What are the closing costs?

If a rate fluctuation of around 1% is a deal breaker, you may be running too tight of margins as it is.
