Reporting - If you are raising capital from others who will benefit from the ownership of the park, establishing clear processes and timelines for reporting, distributions, and delivery of tax documents will be critical to providing a great experience to investors.

Maybe start with email (seeing it quick and cheap) and then move to mail and continue alternating throughout your life cycle of marketing Good luck!

Similarly if your bank has an app that does mobile deposits that's probably worth looking into.There probably are apps like you're talking about and I'm just unaware of them, so it would be nice to see what others have to say.I will say that there are some big property management solutions such as Buildium and Appfolio, that probably have apps which tie into their system and provide some of the tenant and building/portfolio tracking that you're asking about - but those systems as a whole aren't necessarily cheap, either.Personally, I just make sure to carry around at least one envelope - so I can always do "back of the envelope" calculations when necessary :D 

Homes are cheap and the rents are good. 

Rest of landscape could be rock/mulch (something cheap, but looks good).

If you see this property surrounded by others that are also very cheap or cheaper (I see some multis for 10k) , that can be a red flag.

I am sorry to hear about your first experience and hope you got it very cheap and make some profit when you resale.  

Attracted cheap people and had 2 retaliatory 1-star reviews (1 of them they got mad that I woke them up at 11.30am, when their check-out was at 10am - airbnb deleted that review a month later - too late), (the other was a family that booked for July 4th, wife booked and husband decided he didn't like, so they left.

That's just way too low for me to feel comfortable...even in an extremely cheap city.

The acceptable means of delivery are: In person, by certified and regular mail or taped to the inside door of her residence(room in this case).
