Any recommendations or advice is much appreciated.Disclaimer: I do not own any properties yet but do own a small landscaping company which is what I am asking this question for.

Besides the obvious that your place could get gutted and cleaned out of anything valuable, there are a number of scams where your listing gets posted to Craigslist, someone else gets access (IE via your lockbox) and "rents" your property to unsuspecting victims.If you do collect fees electronically, don't use Paypal.

I'm thinking about getting large landscape stones to create a barrier. 

I've worked as a licensed athletic trainer, a maintenance technician for a local school/church, a package handler at FedEx Express, and I own and operate a small landscaping company. 

While I only have about 25K to start my investing career, I thought of an interesting way to potentially acquire the rental property...My friend owns and operates a relatively large landscaping company in our neighborhood. 

You should then receive a physical collateral file if not already an electronic one - Collateral file is a a file which contains all of the previous mortgage paper work including things like alonges, deeds, borrower personal information such as bank accounts and credit scores at the time of the sale, pretty much all the paperwork submitted, required at the time of the sale. 

I would double check that there aren't any common utilities you will be payingMissing landscaping?

You don't want to deal with support calls over troubles with electronic gadgets.

Landscaping can definitely increase ARV, but may make more of a difference when it comes to first impressions of a buyer/renter.
