Hello,
I actually started my investment journey house hacking in Inglewood and share with clients how to do the same, usually with long term goals for ADUs etc when there is sufficient equity. I would suggest exploring using a 401k loan as downpayment, we have lenders with access to downpayment assistance programs but there are typically income limits or higher rates than are counterproductive to getting assistance if your paying $1500 more a month. When you say you don't have much saved, I think we need more context, most loan programs we use for 3-4 units require 5% down, so your ideal savings rate will be around 5-7% of the avg purchase price in the area. You can represent yourself and use commissions towards closing cost, but I would also warn that depending on your experience you may benefit more from having someone who has been around the block advocating for you. Given your stronbg income, I always advise pretending you have a mortgage and paying it into your savings, even if you do not intend to may more than $1000 things happen and repairs pop up so you will need and want reserves. Stay the course, reach out if needed!
