Looking at the data it doesn't appear that house prices go up dramatically.

The property value has increased dramatically over the past 5 years, 100K.  

In fact, we try live on my partner's income (the smaller one, though our spread isn't quite as dramatic as yours) and invest mine in a combo of equities and real property.I would caution you to tread lightly and do lots of up front diligence before buying a commercial entity and quitting your day job.

So our priorities are as follows:1) Make sure everyone is safe2) Find out which tenant's are displaced and how we can help3) Repo out the damaged house/s and follow proper protocol to prevent mold (see article on my website)4) Doing contracting work for other folks 5) Collecting rents for month with a 10 day grace period and working one on one with dramatically impacted tenants (sounds like just 1 or 2 for us)

By 1031 exchanging those condos that each practically doubled in value, Now have $160,000 cash flow and in 4 of the apartment complexes we have dramatically forced appreciation too that we will either refinance and take all that appreciation in year 4 or 5 of ownership or at that same time 1031 exchange for a larger property at that time.  

Get multiple quotes, the costs can range dramatically.

Prices have risen dramatically as I'm sure you know just like everywhere. 

Now, your soil profile will not change that dramatically over your life time... and if a couple of inches of topsoil washes away, it will not affect the pile.

As long as you have a fixed loan/mortgage, and the rental income isn't at a high risk for dropping dramatically, you are covered regardless of what the market does.

So many people in their 70's and 80's have to dramatically change their lifestyles because they can no longer drive.
