For example, after Hurricane Ike during my time in Houston roofing costs spiked bc materials were harder to get a hold of etc.The bottom line is if you put something together for yourself get some trustworthy contractors, talk to them, get some bids, and from there you'll have a true understanding of what your costs are.

Check for spikes in tenancy, and significant deviations in regular expenses.Kenneth and Andrew made good comments.

I haven't been able to find any evidence of property values spiking (or even increasing at a higher rate) since that Cerner campus was completed.  

I have also seen a spike in NOD's.

The cash flow is very seasonal too and if you are in the MHP business you want steady cash flow, not spiking revenue.  

The amount of homes for sale (in Collin county) has spiked significantly higher this year.

When the courts get around to ordering them to pay their bills, property taxes are likely to spike and will likely lead to drops in real estate values.Here's an interesting story to ponder. 

@Spike Scarberry I’m with @Dawn Brenengen on this.

Just like MLM  real estate has been attacked by the dream merchants  IE real estate guru's its a great gig for them  they make boat load of money.I like the line from the Traffic song   Low Spark of the high heeled boys.it goes like this" the man bought a new suit on your dreams "  and that was written I suspect in the late 60s to 70s.. :)

For example, Florida's population has been growing for a while (happen to check it in another BP post) and also supports by low unemployment rate (there was a big Covid spike but recovered since then).
