Don't put a high list price based on what you want, needs to be based on solds

The programs he brags about are no more than searching Zillow and Craig’s list for key words.

Call every local investor agenda (look at the agents that have investment property listings and call them) and call every local landlord that owns multiple properties (you can get lists off of Deal Machine).

As expenses fluctuate (property taxes, insurance, maintenance items, etc), the cash flow will be up and down and unreliable.

In reviewing the side-by-side comparison of Invelo plans I do NOT see any skip tracing feature listed.

Your renters will destroy these items and want you to replace them. 

What off-market really means is that the seller refuses to sign an exclusive listing agreement with an agent but tells the agent if they bring them a buyer, they'll payout a commission.

If not I'd confirm with the listing broker and then add a buffer. 

Having a GC that will provide good documentation, itemized receipts, etc. will make the process much easier I've noticed.
