Thank you very much, @Matthew Kwan! I appreciate the advice and introduction to @Albert Bui!
@Kristen L Garner, thank you for the kind words and the guidance (including the bonus tip)!
@Albert Bui, I'm grateful for the quick response, insights, and interest in my journey. To answer your question, here's my situation:
My wife and I own 18 rental properties (all SFHs and LTRs) - 10 are paid-off. With the exception of our home, we never put the loan under both of our names. I reached my 10-mortgage limit under Fannie/Freddie. My wife has 1 rental property mortgage under her name. To capitalize on her Fannie/Freddie mortgage capacity, I transferred 4 paid off properties to her name, so she can do a cashout refinance and purchase more rental under her name. My post was originally meant to figure out what we should do once she reaches her limit, which would be at the end of this year (assuming that we refi 4 and purchase 4), but now I'm also wondering if we should handle this year's refi and purchase strategy differently.
