looking at a mobile home for sale on about 1/2 acre of land. 

Made several attempts to set profile picture to no avail on both computer and mobile site.

@Walmsley Gedeon take a look at Cozy.co - its a mobile friendly platform that you can use to manage tenants and have them pay rent online.

II want to scale rather than buying SFH by purchasing mobile home parks.

However, if you model what the above mentioned park did, you could likely buy an RV or Mobile Home park that was already zoned as such. 

I put  40gal WH in mobile homes, let alone a whole building running off of one.

I suppose running a mobile-home park is "landhacking" in some ways. 

At one sale, somebody, not to say the person losing the property, burned the property to the ground. 

Income that doesn't burn principal.  

I would be very interested to hear from long time investors who have weathered the storms either crashing-and-burning and coming out stronger or simply getting through the cycle bruised but not battered.Having searched for a topic and thread like this one, I don't think there is one quite exploring this aspect of real estate investing where we lay bare all our failures but it would be incredibly instructive to us newbies to learn from those who have gone before and come out the other side weary and with scars to show from the battle.Hope you will find int in yourself to share so those of us who are new can learn.
