Like any job, if you don't enjoy it, you won't like doing it.

This property will be a pure short term rental investment property.  

I really enjoy my job but it is extremely demanding and leaves little room for much else. 

Sounds like you are on a good path to enjoying life and being successful in whatever field you decide to pursue.

In my head, it would make sense to try to soundproof any shared walls and maybe even fence half of the yard so each guest has their own space to enjoy. 

My last 95% LTV Home Possible loan was the month before they changed it to being 80% AMI for census tract.But if triplexes and fourplexes were somehow that cheap (so cheap that low income people could buy them, and enjoy the cashflow MONSTERS that they would thus be), wouldn't the prices just get bid up?

I especially enjoy the Italian market and all the shops around it.

Although some people do get nervous making these investments out of state, many people enjoy not having to watch over these properties, as the distance will keep you from feeling like you have to check in on them all the time. 

Purely my opinion.

What is your one best 'referral' resource to learn and acquire the 'chops' it'll take to enjoy a decent living?
