Most of these properties are fixed & flipped above market worth, and the bid side is sliding as you're paying over market.

I'm not saying that's what you have to bid, but you want to submit winning bids, not just random bids. 

So I wouldn't trust a bid from a Contractor unless you pay them, the other guys will just mail it in.

We gather all documentation into a Google Drive folder for potential buyers, including:Renovation details (brochures, warranty cards)Pre-listing inspection reportPre-listing appraisalWell system documentationSeptic system documentationSharing this folder with agents and on the MLS helps create transparency, leading to bidding wars and waived inspections, often resulting in offers over the list price and fewer repair concessions.By identifying properties that fit the rural buy box for entry-level to mid-priced buyers and tackling major expense items upfront, we remove risk from the transaction.

the est min bid starts at $4600, adjudged value 128k and in the notes it states: LAND/IMP; SOLD SUBJECT TO 2022 TAXES; HOMESTEAD.

Redeemable deed (1year) with 20% premium.Given: For example, in past auction 1 property was due $5k taxes and bidder won with bid $20k.

Bid on property 2 and see what that brings.

You’ll also need to determine your project delivery method (design-bid-build, design-build, etc). 

As you know labor is the biggest expense and sometimes the owner can float out a lot of the expense on time for the products.A good example of this is a 4 plex that needs complete rehab minus major electrical or plumbing and the bid from the contractor may be $44,000 in labor ( $11,000 per unit )   The contractor may suggest I will take half of the first two years of rent or the equal of same. 

It has been hard finding a place that 1) Doesn't get bid up by cash buyers that we can't compete with 2) Doesn't have 10's of thousands of capex out the gate3) Is in an area that I'd grade as C+ or better.
