I've got an uncle who believes in me and has the capital to back something if I can bring him a good deal, he also has some development expereicner and seems to think letter spamming is the right move.

.$900,000 appreciation if you are considering a 20% capital gains tax(or some hybrid between 15% capital gains tax and 25% depreciation recapture).With that said, if the property appreciated that much over a 4 year period, even if you lost money on cash flow, the appreciation more than made up for it.

Does couple qualify for capital gains exemption? 

This structure ensured the project moved forward without financial pressure or personal capital risk.How did you add value to the deal?

When investors loop a broker in early, they can usually get:• A no-cost opinion on whether the deal is actually lendable• DSCR and Non QM pre-analysis using real underwriting criteria• Feedback on whether the numbers support all cash, leveraged, or walk away• Updated rate scenarios and leverage options based on real-time pricing• Risk red flags that free tools do not highlight• Confirmation of what lenders will and will not count as qualifying income or rent• Guidance on capital structure for BRRRR, flips, or long-term holdsIt is similar to working with a financial advisor because the tools matter, but having someone who knows how to interpret the data matters more.

This isn't for everybody and you do have to pay attention to market conditions to protect your capital.

His contribution is the property/land & your contribution is the capital required for the construction. 

Sellers may also see tax advantages such as spreading out their capital gains tax hit.

That will be the most affordable capital with the ability to build meaningful long-term relationships.

He put in the capital and I put in the expertise and the work.
