I would like to know more about ways to use OPM  The only way to determine if the home is going to cost you a lot down the road is by determining the age of the mechanical systems & if the structure of the home is sound. 

My son (age 24) however, is an independant contractor / self employed and is trying to buy a house. 

However if you have enough reserves, 6mo or greater then I'd say chance it but a couple of missed payments from the tenants and you have to foot the payments out of your own pocket.I'm all for taking risks but I think you really need to evaluate the age of the major systems so you don't get hit with a bunch of cap ex all at once as well as your reserves. 

I'm an independent agent here in AR and I write a lot of rental property, with ~6 preferred markets and if the properties have some issues, age, claim history etc.

I recieved my real estate license at 19 years old, and you will face difficulty in closing deals due to your age as I did.

Eg find contractors in ages out of state.

These requirements are solid, keep them: Application: Everyone aged 18 or older must complete an application.

The age-old question: "How do I get more clients?"!

I fund land flippers in all these states and at your age I would be hunting down a parcel now U want to eventually move to...

In Reno and metro areas, insurance companies primarily focus on roofs, the age of the building, wiring updates, and water pipes, as mentioned @Cameron Moore.
