You'll need a broker of record if the existing broker is exiting the business. 

Hi Timmy, I recently interacted with the City's Planning staff about a listing that had an existing structure that seemed to at least have potential for an ADU.

With the technology available today allowing lenders to more easily monitor deed transfers, and interest rates on new mortgages double the rates 2 years ago, I would only do a sub to transaction if I were sure funds would be available to pay off the existing mortgage should the lender decide to accelerate .  

Best,GZHello @Gabriel Zepeda,As @Andrew Abeyta correctly mentioned, there is not a direct and clean way to use 1031 exchanges to pay off debt on your existing portfolio.  1031s are great for lots of things, and they're really important to serious investors; however, they are not very useful as a tool for deleveraging. 

Your licensed agent will also be versed in fair housing laws to help you avoid breaking rules and statutes you might not have known existed.2) Hire a property management company which will handle advertising, screening/placing tenants, collecting payments, handling repair calls, etc.

Depending on when you bought your existing, some values have gone up quite a bit and you may be able to borrow against equity as an option.

A pre-existing LLC cannot, but if you want an LLC for asset protection reasons your Solo 401k can own a newly formed LLC and that LLC can own the duplex.

In that case, it may make more sense to convert existing components of a home (attached/detached garage) into additional rentable space rather than building an additional structure.

An advance against your cash flow from other existing real estate.

But, I am considering buying a home 300+ miles from me that I can use as a vacation home for myself a few weeks a year and do short term rentals the rest of the year.Question: Can I get a second home/"vacation home" mortgage (10% down) when I don't have an existing first-home mortgage?
