One of my past clients had success this morning lowering property taxes based on a CMA I had provided using accurate and recent sales in his area.

Could use any advice in regards of methods for property acquisition, market analysis, in-depth BRRRR methodology (preferably the refinance aspect) and determining an accurate ARV with the most need in comp analysis.

I am able to pull the owner names from the public record, but many of them I am having the hardest time finding accurate information.

It's more accurate to say an LLC is a legal entity -- not a tax entity...at least at the federal level.The primary benefit of making an S election is the ability to reduce SE taxes by paying out a salary to owner-employees.If you're above the phase-in threshold for QBID (20% business deduction) and the trade or business isn't a Specified Service Trade or Business ("SSTB") an S Corp becomes even more compelling due to its ability to pay out W-2 salary and influence the QBID.There are a few other benefits as well as disadvantages to making an S election. 

@Carter AndersonSounds like you may be in underwriting stage, if this is accurate I would underwrite without premium especially if you have no comps in the area to go by.If you do end up getting the property you can try to sell it as an added amenity compared to other properties and try for a premium. 

But it turned out the closing docs were based on estimated numbers at first, and when I received the final version, the numbers were more accurate, and amount due was less than expected.

Through this I’ve gotten comfortable with the Rental Calculator, I’ve found ways to get public information, information from management companies on better more accurate numbers for utilities (mine were over, but I left it that way), created relationships with a broker/agents/other investors who now know me as a numbers guy, and those same people seem willing to continue to work with me reach my goal of owning my first investment property (whether or not i house hack it).I’m pretty pumped about that. 

The information's not bad, but like you said it's not entirely specific or accurate. 

I started last night but quickly learned I don’t have the most accurate numbers to put in the calculator

So Im pretty new to the BP community and recently stumbled upon Mashvisor, a website similar to Zillow, Realtor and typical MLS websites only its dedicated to investors, running the comps and showing potential returns/COC scenarios etc.Wondering if anyone else uses this and if you find it accurate?
