I have been contacted by multiple corporate housing companies that would like to secure long-term leases and then operate it themselves.

It's essential to conduct thorough market research to identify areas with potential for rental income and property appreciation.Financial Considerations: While purchasing a property in Oakland may allow you to build equity, you'll need to evaluate whether the rental income from house hacking covers your mortgage, taxes, insurance, and other expenses.

Aim to purchase and renovate a property for resale, with the ultimate goal of acquiring additional income-generating rentals.

Passive  income is fairly consistent - especially to the bank.  

Make sure they are experts in your market segment too. if you want to do low income housing, then a great manager who focuses on B class properties isn't going to work.

Would personally guaranteeing the loan be something that would pierce the corporate veil? 

Essentially, from the buyers prospective, this is a “penalty” paid for either having poor credit (bankruptcy, 90 day lates, overburdened with debt) or lacking income.  

The advantage is that, by living in the smaller unit and renting out the larger one, you generate a lot of rental income!

Since you never formally owned the asset, that income could be seen as regular income.

Typical rates are 8-12% of income either monthly or yearly depending on manager.
