Just tell them what you're comparing them to..This is assuming the data you presented above is the only data to be considered..Hope this helps a bit!

Thank you to everyone who did this first, and for the invaluable lessons that I could not find in my years of study prior.

I have seen many investors make the move to buy one or more proeprties and those properties even without renovations double/triple in value. 

Our houses have gone up in value and so have the rents we're getting.

@Hank Thomas it’s common for them to start with a “desk top appraisal” (at no cost) which means they will pull from their data source to get a valuation (usually very conservative) without going to your property.

I have a residential lot in an area that seems to be going up in value quickly so I don't want to get rid of it.

You didn’t spend the other $50k in value increase so you can’t depreciate it.

Residential overview by state then by respective MSA here:https://www.nar.realtor/resear...Commercial and Industrial Overview trends here:https://www.nar.realtor/commer…Many other information conglomerates will publish data (ie CoreLogic), usually quarterly or annually.  

Also, make sure to square away the utilities, find out if you owe taxes for 2021, as mentioned above get the data on the tenants.

If you can qualify comfortably and are willing to take the risk, then jump.Another option is to get into contract to purchase the new house, close and then sell the existing one which mitigates (reduces) the risk of owning two properties in a market that may decrease in value.
