i have looked into the Landlord locks as mentioned but have not used them. i have one student rental where i use an electronic lock ( that i can control from anywhere, change codes etc.), but the bedrooms are regular keys, as @Jonathan C. mentioned for the front door, the unit is set up to send me an email when the batteries are low. i also have another student rental ( 8 rooms, 2 entry, 2 units + utility room) one master key and each bedroom has its own key that will get students in the entry, there unit, and there own bedroom. had a locksmith do that one. cost me a few hundred dollars with keying and supplying the locks ( 13 total ). i like both setups but may look into the landlord locks again for my 3rd student rental i just purchased.

Even with all I mentioned and forgot to mention above the real estate money was easy moneyHere is the house https://www.corcoran.com/nyc/Listings/Display/4778829?

As mentioned.

Not to mention the general PHX market has become expensive and people have already been looking for cost efficient alternatives in the northwest and southeast corners of the valley. 

What happened with the young couple you mentioned invested with them 

As Nicholas mentioned, house hacking is a great way to dive into investing.

They don't mention anything about paying payroll taxes, workers comp, complying with laws, etcReal estate agents can have a team around them where they do have employees if they have admin/support or marketing team.Regardless, if you want to interchange small business for commissioned sales people in my post you can.My post was mentioning that service providers in the real estate space are incentivized by their advertisements as it will increase their annual income.

I know a few investors that do it here in Tempe, Mesa, and Glendale - not to mention you can do it in Phoenix as well. 

To do this, they have a team consisting of an inspector, a makelaar, and renovation professionals.However, as Ken M. mentioned, having someone trustworthy there to manage everything would also be a key factor.

G'Day Alejandro,As a few have already mentioned, take a peak at Toledo also.In my opinion lower potential for long term appreciation but solid/"boring" cashflow.I prefer my portfolio to be "boring" but cashflowing lolLow entry points (Sub $100,000), high rents (Above the 1% rule).Blue collar working class decent folks that will stay and pay.Depending on the area but no derelict homes, yards well kept, cars with wheels and all tenants are employed.Plus, all are sophisticated enough to pay rent online so property management doesn't have to collect rents with bullet proof vests and shot guns lolI'm bias toward Toledo but it's worth considering.Wishing you much success
