But you already own a property and maybe you can maintain objectivity way better than me. 

Also, get in the habit to budget for property management (8-10%)  even if you're self managing. 

@Fernando CardonaThere are a couple of items to think of here.You might be considered in the business of issuing money.The pro is that the interest on the loans you borrow from will be deductible against your income.The negative is that your income might now be subject to self-employment tax.You should think of the money you earn from a post-tax perspective.if you are borrowing at 6% and lending out at 10% - you are only making 2% if you are near the 50% tax rate(fed income tax, self-employment tax and state income tax).Depending on how diversified you are - one person not paying you back can make you lose all your gains/income

This leaves you a buffer..... and time to fly out and inspect it your self.

I have a current 457B plan which I am permitted to self-direct through a brokerage account at Charles Schwab.  

One better would be self storage. http://bit.ly/2CILuJ2

Right now I self-manage 6 of my units and use property management for the others just because I’m stretched too thin w full time job and a family and i also do a flip or 2 per year.

I self-manage all my properties (7) and have friendly relationships with all my tenants.

well first off this being a landlord site.. and a positive cash flow site generally speaking.. most will tell you are nuts to buy this.however if you can get the property to just about break even maybe lose 100 a month or so and you have a prime Socal asset that someone else is paying off your mortgage and you think rents can go up a little.and you can EAISLY self manage based on quality of the unit .. incredible tight rental market.. that mitigates a lot of land lord issues.I mean whats the alternative you go 1000 miles away to make 100 or 200 a month.. is that positive cash flow going to change your life..is 100 a month negative going to change your life.now this is an extreme.. but i owned a home in Palo Alto that i chose to sell back in 91 because it would have been 300 a month negative.. well that negative within 36 months would have been positive.. and i sold for 500k and today that home is worth 3 million.... and once it got positive it probably would have been positive up to 2 to 3k a month coming into the 2010's.... and someone else would have paid for my home.. plus grade A tenants at all times.. being prime Palo Alto.so thats one extreme.. its really only in low to no appreciating markets with tougher tenant bases that turn a bunch that positive cash flow becomes more acute or for those that want to one day live on their cash flow and be in the business of landlording.. thereby acquiring 50 to 100 doors. 

If you are running into such high number due yo wanted to have self contained units, maybe you should look into billing back your tenants for utilities.
