While in theory they sound good, they can be non renewed at the end of the period - so say in 5 years... plus the interest rates can fluctuate.  

If your goal is to hold the property and collect rents over the long term (lets sat 10+ years) then the fluctuations in the middle do not matter as much. 

The market fluctuates, as would an appraisal.

.-  Also, regarding the market tanking, how much fluctuation should one expect with rental income? 

25% avoids MIP - and is enough to cushion minor property value fluctuations.  

And today's "most interesting" exchange so far from FB Marketplace.Yesterday, a woman had been messaging me with questions about the rental, for her boyfriend, until I finally told her to have him call me.He called this morning, says he's a freelance dance instructor, and makes between $20K and $30K a year, it fluctuates.

To get 80% of local price fluctuation you have to add at least next quantitative variables:- real estate taxes appreciation rate,- purchasing power (money left after immediate needs - taxes, insurances, food etc)- net/reverse migratory stream,- CPI,- construction of new homesNot to mention subjective variables:- confidence (will i have enough money to pay the mortgage tomorrow?)

It’s great for both cash flow and for steady income because it fluctuation rate is little in comparison due to its relative diverse income and lower GDP.

The stock price can fluctuate very fast and you lose it all in a day.

This provides little room for market fluctuations.
