My focus is on purchasing a single-family home to set up a lake house or cabin to own and self manage from my home in Bergen County, NJ.

Property Radar is super robust. 

I did purchase a four plex in Napa, CA a couple of years back, a super long rehab and now getting ready to get tenants.

You can exclude gains up to $500k if you're married, $250k if single.

Once that avenue is exhausted, go the single family route using conventional or government financing. 

Nearly two years ago, I purchased a single-family home in River Forest, USA, which required extensive renovations.

These are the different properties that are included in the 1031 exchange requirement: commercial buildings such as offices, schools and different establishments that are important for the population, as well as single family rentals, multi family rentals, industrial facilities, and even raw lands are included in the like-kind.

In a total package deal for a single family or multi what do you look for?

Finally, you post that your market is super hot for buyers, but then you don't mention what market you are referring to. 

Quote from @Katie Accashian: I am located in Lakewood, CO and have my property listed at market value and haven't received a single message in 2 weeks.
