My hair dresser is a tenant, my current handyman was referred by a tenant, I rent to the children of subcontractors I hire,  I rent to my the children and friends of my current tenants, I refer tenants that need help to agencies where I have tenants working, I eat at the restaurant owned by a tenant.

As my children would say (when they were very young)...NO TAKE BACKS! 

Occupants can be small children.

In fact, there have been several interesting developments in the area including a million dollar home subdivision and a new Children’s Hospital being constructed as well.

I own properties in the 380 area and I completely agree with you, the real estate growth potential from Denton to McKinney is HUGE (especially when the DNT construction, PGA and Cook Children’s are completed).

I received a nastigram text from a neighbor who was upset that the dog was on their porch/property (again), because they fear for their children. 

I was 25 and my wife was 23 when we had our first baby.We fell for the “American Dream” and bought a single family home.Oops.Terrible mistake.Yes we have equity in the home but we could have equity AND cash flow.We should have bought a multi and then used our cash flow to buy ANOTHER multi.From there generate enough cash flow to pay for the LUXURY of a single family.Supplemental income is a very beautiful thing.Is it pretty and attractive in the beginning years of marriage and children to live in a multi?

Depending on your area and number of children being cared for, you may not be able to anything legally. 

Parents can give up to $15K per year for children.

Some examples include family's with adult children and/or an aging parent that needs to be close to family/care.Lastly, I wouldn't necessarily agree that if something was possible a prior owner would have done it already.
