My thoughts:- best advice above is to get a good attorney that specializes in evictions. - Who ever told you that only 30 days notice is required does not know CA law.  

Quote from @Basit Siddiqi: I personally would not buy real estate with a retirement account.There are just too many headaches that are not worth the potential increased return.Some headaches when it comes to investing in real estate with a retirement account1) LTV values are less and harder to find lenders.2) Potential to sell or partially distibute the property if you have to do a RMD(Required Minimum Distribution)3) If you run out of cash and have to make a major repair, you may be out of luck and have to sell.4) Having to potentially worry about UBTI(Unrelated Business Taxable Income)I would personally invest in stocks/bonds/notes with a retirement account.I buy deals with cash and use a ROTH SDIRA so there are no RMD's.I buy at huge discounts to retail.

The rental market is already showing signs of recovery:Spring Is Coming: Historically, the rental market picks up momentum in the spring as tenants prepare to move during warmer months or ahead of the school year.Early 2025 Trends Are Positive: In just the first week of January, we’ve seen a dramatic increase in rental applications, suggesting pent-up demand from renters who delayed their searches in November and December.What Landlords Can Do NowTo make the most of this recovery, consider:Refreshing Your Listings: Update your photos, descriptions, and pricing to ensure your properties stand out.Offering Incentives: Temporary discounts or move-in bonuses can help fill vacancies quickly.Being Patient: The market is already bouncing back, so don’t panic if your property takes a bit longer to lease than usual.What’s been your experience?

Eric, First, Good idea on searching for a realtor specializing in STRs.

I'm unsure if you would be able to combine both loans given that the HELOC is tied to a different property than the one you got traditional financing on.A work around is if you are able to purchase the new property with the HELOC at a significant enough discount, bring the property value up via renovations or additions, then refinance the property, pulling out enough money to repay the HELOC. 

What areas do you specialize in?

I got a reasonable discount on the purchase price, and it has made me a good amount of money over the years.

We focus and specialize in "on market" MLS deals. 

No magic or special system.

Also when you are under contract and get condo docs, make sure to read the meeting minutes (for the past year if available) they will indicate if there are any talks of an upcoming special assessment (which you don't want).
