Does this sound like a great idea regarding being a landlord and starting a real estate empire?
This can be done, and there have been many good suggestions on things to do and watch out for.  But to my shock I don't see anyone offering any words of caution about property managers! Whatever you do, don't assume they have your best interests at heart.  Do not assume that "no news is good news" and that if you aren't hearing of problems and are just collecting rent checks, everything must be fine. You can easily end up with tenants you would never have allowed yourself, or tenants with pets that you would not have allowed, etc.  Especially if the manager doesn't want you to have a vacancy and potentially lose you as a client, they may very well lower their standards just to get the place occupied.  And a year or two or three later, you may find yourself looking at a very large repair bill and wonder how on earth it could have happened when you supposedly had someone looking out for your property! There are quality, ethical property managers out there.  They are not all bad to be certain.  But whatever you do, check up on them.  And with multiple properties - especially if in multiple areas/states etc. - this can be nearly a full time job in itself.  As the saying goes, "Trust, but verify".  I have never found this to apply more than with rental properties and property management. Don't leave anything significant to them 100%.  You can't even assume that a rule like "all expenses over $50 must be cleared by me first", as that can simply mean that they don't bother to come to you for certain kinds of repairs that would cost more than that, or that they just get them "taken care of" by their own person (done poorly, illegally, etc.) and never tell you.  Never trust their choice of tenants blindly.  Visit the place yourself at least every few months - a quick driveby at a minimum or better if you can, arrange a reason to walk through the house personally.  Check the back yard, never assume that the front yard is indicative of anything else.  Never assume that a "no pets" rule will be followed, or that tenants wouldn't lie to the management about having pets.  Never assume that the tenants won't move additional people into the property as well. Always expect a bare minimum of 1 month vacancy every year, and an additional minimum of 1 month's rental revenue in unexpected maintenance/repairs every year.  This is at a minimum!  You might do much better than this, and have a high quality tenant in place for years who costs next to nothing in extra maintenance.  But do not count on it. Rental real estate investing looks so simple on paper, where it's just numbers.  But reality has a very rude habit of surprising you when you least expect it. After all, no one expects the Spanish Inquisition! Good luck!
