I have a friend located in Las Vegas that is searching for a home.

Depends on location, condition and price.Sometimes you get a good tenant before the previous moved out, sometimes it takes few months

Would discuss with a couple of realtors and get their opinions on location/demand for specs first.

Hi @Natasha Richardson,I wish I could answer your question more directly but it all depends on the location, quality of property, recent sales activity, supply and demand.

If so, where is it located? 

The next time some non-landlord posts in this forum about how bad low-income -housing fixer slumlords should feel for taking advantage of our C/D-class tenants, I'm going to try not to jump down their throat, but no promises. 

Well their starting pay in my location is slightly above the minimum wage.

I am looking for the best locations in Pennsylvania to invest in rental properties.

In Texas, for example, these are included on the Statement of Ownership and Location (SOL). 

I have a property I brought in Maryland near Andrews Airbase, good location right.
