You would be increasing in a variety of ways: your exposure grows because you would be making more transactions (talking, financial, relational) because of "growing" the LLC to house more than your current RE business, you would be introducing different types of liability due to the different asset class and length you would hold the assets, and the bigger any LLC becomes the juicier it looks for anyone considering to sue you.For flipping properties I would highly recommend looking into the Series LLC, also.

Also, if it is high, consider lease length of the tenants.

If so, what is the length, of the warranty?

That said, the structure you outlined is useful for readers conceptualizing and structuring arms length deals.

Nothing is stopping you from increasing your monthly payments to shorten the length of the loan (assuming no early payoff penalty), which will get you the same benefit (less interest over the life of the loan) but with much more flexibility.

Further a poor review is warranted and should be placed online for others to be aware of before starting the length qualification process.

Your mom’s house likely will have no capital gains tax due upon sale based upon length of ownership and her time in the house.

@Jaysen MedhurstIf you are not part of the LLC, Title is held by the LLC, and the member(s) of the LLC are not related to you, then it should qualify as as arms length transaction.

In California, you have to add "and all in possession" wording to all eviction paperwork to cover those who is not on the lease document but who can claim tenant rights by the length of their stay.

I have written several times on here at length if if you search my posts.
