My accountant strongly advised me against real estate investment, maybe I should get rid of him and use yours.
I have 3 properties: 1 rented, 1 for my parents and 1 for me and my wife. I have been practicing for 4 years now, and feel the low mortgage interest rates days will be behind us soon. Plus it depends on where you own properties, regardless who manages it, your net will not be $300-500 a month per unit after taxes, mortgage payments, management fees, community fees and miscellaneous expenses. It's a lot of work, even though the rental market is hot now, you still have to put your own six-figure money to purchase the next property or borrow from lender and carry more debt.
My next property would probably be a mid-end range, 1-2 bedroom, $200-400k, near tourist destinations or busy hotels, and list it as per day rental through Airbnb or Vrbo website for $100-200 a night. This is a great property for the short-stay market, like families or business travelers who want a great alternative to hotels. Even if you rent such property for 10 days out of the the whole month, at $100-200 a day, you are are looking a better return than a property you rent a full year. If I owned 20 of these properties, I would net $200-300k a year at the low end, or 3 times that amount if they were rented 90% of the month. The other benefit, if you own these properties in different cities, they could be vacation spots that I would use for myself and family and save on the cost of staying at a hotel.
Maybe I should run this by my accountant and get his support.
