My wife and I live right next door in Marietta.

But the owner occupied rates and down payment can make this a great way to add doors, add value and have some income. 

Being a Canadian citizen myself, investing in the US has allowed us to open many doors we would have otherwise not been able to open. 

from what i heard, I can tell him to leave but if he/she doesnt then i can change the locks on the door and ask to leave and so oni would appreciate someone sharing any info related to questions above. 

That's actually pretty significant.. in a lot of cases it's around a 20% hit to profit per door for most landlords.. 

If you dig into the guys who are pulling down large numbers of doors in a year, they are doing it out of state and they have money partners. 

I will be paying about 45k per door for these units and they will be paying me $3000/yr each or $18,000.

My early goals were to buy so many houses at $200 a door.  

Scale and iron build up will excellerate wear and tear on anything that water touches including dishwashers, water heaters shower doors etc.  

@Sam Shueh its 720 sqft 2/1 the interior just nees TLC, needs new cabinets, and tile in the kitchen and carpet, paint, the whole interior,couple lighting fixtures, It has a finsihed basment which could bump this property to a 3bed if they buyer wants the house was built in 1952 exterior looks really nice, the owner pays a fee to have everything serviced the roof will probably need to be changed in about 2 or 3 years, foundation is solid, garage is solid no cracks or signs of leaking.
