As a result, I've been driving for dollars and mining the county auditor's website for properties with delinquent taxes.

In Nevada, property taxes DO NOT reassess on the sale.  

Also, this year of 2022, the actual deadline is Monday, April 18th, thanks to an obscure holiday.Where can I find a great accountant to prepare my taxes before the deadline and avoid an extension?

Purchase price: $500 Cash invested: $1,123 Sale price: $25,500 A seller got behind on taxes for this 1.4 acre parcel in Colleton County and it was sold at auction.

I am thankful and looking for feedback from our professional tax preparers. 

And you forgot to count the tax savings as returns.

I have been trying to break into the residential space on my own by driving for dollars, knocking on doors, sending letters, and cold-calling lists of vacant, pre-foreclosure, and tax-delinquent properties.

couple of questions1. are the taxes correct, will they go up after purchase/reassessment?

I smell a refi in your pipeline a year or so from now, remember this isn't a home loan, so "two years of tax returns showing a profit" is NOT a hard/fast rule at all to get the best terms.

If its a 2-4 unit you only need 15% down using a True Portfolio program and you have DSCR as a back up that uses the STR rents to qualify and avoid personal tax returns or income.
