How do you do a key exchange? 

Here are a few strategies to consider for funding a down payment:Partnering: Like Gregory mentioned, finding a partner who can contribute to the down payment in exchange for equity or a profit share is a solid option.HELOC or Cash-Out Refi: If you have equity in your home or another property, a home equity line of credit (HELOC) or cash-out refinance can provide the funds you need.Private Money: Reach out to friends, family, or private investors who may be interested in lending you the down payment with a promissory note.Seller Second: In some cases, the seller might agree to finance a portion of the down payment as a second mortgage.Live Frugally and Save: It takes time, but reducing expenses and setting aside funds from your income is a tried-and-true method.The right approach depends on your situation and deal structure, but a mix of creativity and resourcefulness can go a long way.

My real estate journey began in 2010 with a three-family property that I lived in, renovated, and eventually turned into a profitable rental before selling it via a 1031 exchange to purchase a short-term rental.My current goal is to acquire my first multifamily property using private lending by Q1 2025 and grow my portfolio using the BRRR strategy.A question for the community: What’s been your most effective way to connect with private lenders for small multifamily properties?

This means that the property doesn't qualify for the extension, probably because it doesn't meet the covenants such as DSCR or debt yield, so the lender is making an exception and is willing to grant the extension in exchange for the $4 million.

Will this cash out has any tax implication on the 1031 exchange already completed?

In December, 2021 REV claimed it would be relaunching RadioShack as a cryptocurrency exchange.

Might it be smarter to offer a slightly lower monthly rent in exchange for a tenant who feels more content.
