@Ken Livingston I usually recommend people take solar panels off their properties, not put them on.

I'm more wondering what people are paying per piece for post cards vs. envelopes.

Lots of people buying.

There was also some minor damage: handful of nail holes in every room, their cat scratched up some of the trim, a bunch of dings/gouges around the doorways and in the bedrooms, marker stains on the bedroom wall.More significant damages: The tenant put glow stars up in the kids bedroom.

I would also stay away from people just starting out, its hard being a 1/2 person operation with a low unit count.Best of luck!

No more than you should become a master electrician, master plumber, HVAC tech,  insurance agent, loan officer, and maybe other licensed people.   

There are a lot of people in this note investing business who pretend to be experts. 

On this specific project, I went for a little more ambitious agenda as the property at hand showed an ARV of AT LEAST 325,000, the property was two story, Property had a converted garage, and boasted a square footage of about 2,400 sq ft.

I have seen COUNTLESS people get a head of themselves on this platform.

I am learning all I can and I can't wait to start collaborating with all the great people on Bigger Pockets.
