<prompt> Human: My in-laws live in California and are essentially homeless having been forced out due to rent hikes and are living in shared rooms in separate AirBNBs. They do not have any monthly income aside from SSI. I gross 230K and my wife makes 60K. In 18 months her salary will increase to 350K and mine will marginally increase. Total gross salary July 2020 will be 600K physicians. Disclaimer: net worth -1,000,000 - student loans 800K current mortgage 200K. Loans should be forgiven through PSLF in 2024. My wife and I currently live in another state and her parents refuse to move states to live with us. We are moving to Southern California work related next year and there are 2 options:OPTION 1- Buy a duplex and wethem inhabit the units until my wifes salary increases 1 year. At this point we will have enough income to buy a separate house for my wife and I. Her parents will continue to pay a small amount of rent to us 1000month to offset the mortgage and also serve as landlords for other tenants. OPTION 2- Buy a single family home, live with in-laws for 1 year and risk my marriage but suck it up. The downside is that I wouldnt be able to generate rental income from this property once my wife and I buy a separate house. TLDR: my in-laws need a house and I either buy a duplex or single family home until she gets a huge raise and we can live elsewhere in Orange County, Ca  <response>: As soon as I read they refuse to move states it was a no too bad from me. If they dont want to move somewhere the hardship wont be so difficult then why help in the first place.
