Would seller concessions benefit the seller in the form of capital gains reduction especially on flips?

The purchase was $375,000 and the rest was used for renovations.My cost bases in the building will be around $740,000.I refinanced the building with a $900,000 loan.I have an offer on the building of $1,400,000Total capital gains would be about $660,000So, my question is after selling the property (for easy math) lets say I walk away with $500,000 after paying off the bank loan.

I would wait until that PPP lowers in a year or two then see if you actually get a substantial gain in savings. 

So I have gained so much from just participating at a fairly low level for a few years, but the people I've met and things I've learned have proved invaluable. 

This also means I don't have the bandwidth to cold call all day to gain traction. 

It is true that the 1% rule is definitely hard to find but most investors are loving the equity plays and appreciation gains every year. 

These investors can provide the capital to stabilize struggling but fundamentally sound projects, potentially earning higher returns than traditional financing routes.Current State of Mezzanine Debt and Preferred Equity InvestmentsAs of mid-2024, alternative financing in real estate, particularly mezzanine debt, and preferred equity, has gained significant traction.

We have gained a lot of real world experience from our 10+ syndications as lead sponsors.

Which brings me to my second issue: I don't believe (but haven't looked closely) that most of these funds are even trying to gain contractual control of the deal.  

Situation:Found a seller who wants to sell but doesn’t want to pay 300k gain all at once.Pure vacation property/second home.
