I began my real estate journey in December, and together with my partners, we now own 10 units and have grown our portfolio to $5.5M.

I love my partner on these projects.

I do have a handful of clients that have ended up using multiple CPAs just due to who their partners were on different deals, and even in those cases they almost always end up consolidating to a single CPA - taxes are enough of a headache without dealing with 3 different professionals who each only have a slice of the whole picture.If you are going to regularly be investing across the country, it doesn't hurt to work with a firm that has State and Local Tax (often referred to as "SALT") internal resources, though typically this does come from larger firms with larger fees. 

I have partnered with a number of production builders that are starting to do what you mentioned.  

For mortgages without 2 years of income, consider non-QM loans or partner with someone more experienced, and don’t overlook creative options like seller financing or lease-to-own.

Private Money= Family, Friends, JV Partner, Colleagues.  

My friend from the Marines Corps is partnering with me and we are just starting out.

Sell 1/2 interest to a partner at a profit to yourself.

My partner and I buy and rehab properties, then refi and hold long term (BRRRR).  

I have a flip I just finished together with partners.
