With more than one unit, the biggest difference is that you have tenants complaining about each other and the property picks up more of the maintenance, like lawn mowing.There is a huge difference when you get to 5+ units as those are valued using the income method. 

There are new laws affecting California transactions in 2024, some of which are very relevant to investors and house flippers.According to the California Association of Realtors, starting July 1, 2024 most 1-4 unit properties that are resold within 18 months (aka flips) must disclose:- repairs, renovations, room additions and structural modifications that were performed by a contractor with whom the seller entered into a contract- the name and any contact info for the contractor for any work over $500- any permits obtainedSo you still can be an HGTV star, just make sure you do it by the book. :)Have any of you flipping in the Los Angeles area been affected by these new disclosures?

So, from time to time we get contacted by someone, that’s probably bought one or two properties in their entire life. 

Once you get more units you can offer to stay at one to wait for other property they desired to come available.

For BRRRR investors, seasoning requirements can significantly impact your ability to quickly recycle your capital.While most lenders require you to hold the loan for at least 6 months (aka "seasoning"),Fabulous 5BUY - short-term bridge financing to help you with investment property acquisition.REHAB - With up to 100% rehab financing, you can stay liquid through renovations.RENT - Tenant in place or future tenant.

Let them work with you on your ARVs when you get serious about a property (don't thow them a thousand deals you see and expect them to do CMAs all day long...make it worth their while).

Based on your question I would also advise you to seriously consider using a property manager.

@Nam Pham  Assume likely an older property on a pier and beam foundation, as compared to a slab foundation?

I, like you, have a handful of my own STR properties that I self manage, and manage just shy of 20 STR properties located in Bryan / College Station, Tx for out of state/country investors. 

I'm unsure what the right path is, but I've been reading about investing in owner-occupied, multi-family properties.
