Hello Shahin and wife! I would recommend how to raise money legally and Partnership forming. Everybody needs a place to live and apartments are one of the best passive investments and it makes money on day 1 if that is one of your goals and it can be a great long term investments.
To do that type of purchasing of a minimum of about 32 units can afford a Property Management Company and still have a positive cash flow and each vacancy does not hurt so much.
You do not need to have any experience to buy them,. Just money. With a Property Management. Company handling the daily operation y'all do not have to be on site everyday.
Good luck to you both!
