I would like to pull out equity from the homes to build either a house on each or an ADU (they are zoned multi-family) depending what makes the most sense on returns and what is feasible.

@Ryan Cousins it's really going to depend on YOUR analysis/projections of what you think the property will be worth in the future.You'll want to compare that to any capital gains tax-savings if you sell now.
