(I have not attempted to offer any Rent to owns since the interest rate spikes.)Whats your thoughts?    

The first "spike" is usually following the first wave of migration pattern that occured in 2019.I am closely watching too if there's second wave out of migration from CA this year as the number of layoffs are gigantic.

There is a few month lag due to billing lag, waiting to see if the spike is consistent, then raising rent, but it works out in the end and I like knowing that the bills are paid.  

How much can your net worth fluctuate daily or even weekly unless you have a huge spike or drop in income/expenses? 

What many of them have in common is that they ignored the market, focused on decent to good areas, ignored the dips and spikes, held for a long time, and purchased when it made financial sense for them instead of trying to time the market. 

My question though is that if the most recent property tax is based on the previous sale price, if your purchase price increases dramatically then wouldn't you get a huge spike in taxes?

It doesn't account for national-level issues, such as the bubble and resulting crash back on 06/07 where unemployment spiked.

I will say that I have seen such a massive spike in the prices of homes over that way that it in such a short period of time rents have not been able to keep pace to provide great returns.The vast majority of all of the properties that I have been working on lately have been over in the NE along the 35 corridors.

Because my guess is if you have rentals in good condition, the rent values will spike.

Or does it spike certain days?
