Ensure the property appraises at its updated post-renovation value to maximize the equity you can pull out.A refinance isn’t a taxable event, but transferring ownership to your LLC may affect depreciation or future capital gains.

Some areas of cities have older stock.

This is something I will have to keep in mind for myself in the future.

You can't even change a lightbulb.You or your family can't use or live in the property.You can't sell a portion of a property like you can sell portions of stocks, bonds, mutual funds, etc.
