So when you know the highest is 6 you can stress test for years 6 to 10 and predict out cash flows somewhat.If you leave it open in year 6 to market that can be dangerous to do.I like floating rates or interest only rates more when a property is a value add and being turned around.

Initial cash flow alone does not always predict future total profits we can understand. 

Today when bringing up the fact that the renovation of the 5 year vacant adjacent property (our project) was increasing her property value by north of $10,000, that was met with a predictable 'Don't act like you are doing us any favors!'.

Expenses will fluctuate but if you ask for the last months utility bills you should be able to get a good idea of the predictable expenses like that.

I understand that we can't predict exactly how quickly the prime rate will go up over the next five years, and that changes in the rate could change the price of each loan significantly -  what I'm looking for here is the formula that I can use to figure this out for several scenarios, and the thing that's throwing me off is not knowing how to calculate total costs under the scenario of a promotional rate that expires.Thanks in advance!

Unless you're the accountant type by nature, that sort of thing will not only drive you batty, it's unlikely to have any actual predictive value.

It costs much less to built correctly the first time all mantainence issues are predictable https://cityzenith.com/

Texas is a great place to invest, we have tons of inventory, and a fairly stable, i.e. predictable, market and tend to weather the national fluctuations better than most states. 

But instead of predicting a crash, it seems the market, at least here locally,starting from January market seems to be warmer again. 

Not sure if you've run a marathon, but what I've found (and what the science tells us) is that the further you go over a marathon, the less like a marathon it becomes - mostly because the predictive value of VO2 Max breaks down and there hasn't been a good alternative developed to predict times.
