I ran into multiples while shopping for a place for my son recently.  

Love to talk shop and happy to help where I can.

My must haves are:  walking distance to train, buses and shopping.  

We keep a close eye on the other expenses including shopping for insurance each year.3.

Each property then has its own individual key we give  to tenants.But to your question about differentiating the ones you already have, those rubber rings they sell at Home Depot or locksmith shops will do the trick.

That is actually a shop here in greeley that works on high end exotics.

You can basically build small commercial buildings (ie: ice cream shop, coffee shop, etc- no high rise) But you can also build a duplex, triplex, or just a single family.

I do believe though this is a trend in many states.. and to set up shop where you go into contract on a SFR  then post pictures of it on craigs list like your the owner seller put signs in the yard bandit signs up a website etc.. ( basically exactly what a Realtor would do with a listing) is clearly selling RE without a license I don't know how anyone can say this is not..

It is in a fantastic high end neighborhood just minutes from incredible shopping centers.

Places to work, places to shop etc...
