If you have equity in your existing condo it's really up to you as far as how you want to "tap into" that equity.

Options I’ve seen mentioned:Splitting the gift across multiple yearsStructuring part of it as a loan (and possibly forgiving later)Using a 529 plan contribution (not really applicable in my case but curious if relevant to others)Setting up a trust or custodial structureOr just taking the lump sum and filing the gift tax form, since it would fall under her lifetime exemption anywayThe goal is to use the money toward real estate investing—either as down payments on rentals or possibly paying off some existing debt.Has anyone here gone through something similar?

And lots of other moving parts that had to come into place: existing relationship with the lender (other loans, savings accounts), great credit, great deal, existing cash reserves.  

I don’t want to keep debating something that clearly works for me but might not fit everyone.Bottom line: I’ve bought an LLC for as little as $10k, kept the existing loan, and never had to re-apply or pay points.

It exists but the borrower needs to have a track record of 5 or more flips exited in the last 3 years.

There will still be the small locations for small practices, but these are now far fewer and will be almost non existent in the future.  

Do you think most people know these tools exist?

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return.5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space.6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

Many times you'll find that these "other people" don't actually exist.

It's a seller finance wrap on the existing mortgage.
