Ensure that the updates are of high quality yet within budget to maximize the increase in value.When it comes to refinancing, after completing the renovations, you can refinance your home to access the created equity.

They apparently do not have time to verify permits (under what criteria units were added or that the work was even done with a permit).To the OP, I fear your property will consistently appraise low when obtaining HELOC or refinancing and that a re-appraisal will not reflect what you are seeing of homes being appraised with an agreed upon negotiated selling price.I am not saying this is the way it should work.

Contact your county tax assessor's office to learn how to find this information (it's usually online and easy).Talk to the neighbors.There are paid apps that may include contact information for specific properties.

HOWEVER, as soon as a property sells on the market (or is refinanced interestingly), the cap differential goes away, and all of a sudden you would see the taxable value of the property jump from $370,000 to $657,000 - more or less doubling the taxes on the new buyer.  

You can do some sourcing yourself through Facebook groups, and online RE communities , and even pick up the phone and cold call some homeowners that may be tired landlords, don't owe anything, and have built up some equity.With enough volume, you should come across some solid deals.
