The longer answer is you may end up having to "police" them to make sure they are not using the other acres which may not be feasible.

As an individual, it is hard to open an efficient, responsible, profitable out of state network because as an individual you do not provide that much value for an agent or a contractor to run around and cater to you.But when you are part of a group that closed on over 4 million in real estate in six months and brought in over one million in local rehab dollars and put 50+ people to work and paid the city inspection office for all the permits, inspections, and reports then people cater you to. 

If it's important to be near the Bay area then maybe consider the Tahoe Reno, NV market because it's only a few hours away if you need to go to the office and it offers a landlord friendly environment, low property taxes, and no state income tax.

Hopefully this incentivizes the tenant to police his friend better.  

I am trying  to purchase a multifamily house , outside of the city where i live it wis about 150  miles from my location ,  how do i figure out the demographics of the area and also the medium income around the area where i am planning to purchase . do i need to look for any big stores/shopping malls or any govt offices around the area to see if the place would be ideal for purchasing the property for renting it .

I heard it was the sheriff office that's taken so long for set out.

remember your first home is not your forever home, it's your first rental so it doesn't need to be everything you want.look for homes where the bones are good, but cosmetically needs love. don't by pre 1960 if you can help it. you'll end up just having to replace all the guts like plumbing and electrical at some point. it's inevitable. look in areas where the path of growth is headed, but might not be currently. think 5 years out. look for resources like your local chamber of commerce to see what businesses are coming in and where. your city planning office should also be on your call list as they can help show where most permits are being pulled for development. follow the money. go to local investing meetups. crowdsource local knowledge and form meaningful relationships. those who've gone before you typically will help out and help you avoid the mistakes they've already made. onward.

Aston at Cinco Ranch is 1min from my office...too funny.

There you will be asked your criteria and then after answering a few questions you will be matched with 3-5 agents or loan officers in your area.

When I asked him to move it, he said the police had visited and that he would move his car in a few minutes.
