Also, I've had several sellers tell me there's no lease, it's month-to-month, just to find out from tenants that there is, in fact, a written lease signed years before that states lease will automatically renew on 1-year terms unless x-days notice is given before end of term. 

Realize not every state requires a license, especially in the commercial space, so not having an NMLS number doesn't automatically make them illegitimate.

Once you have that set-up, RemoteLock integrates with most channel managers (I use Hostaway) and will automatically create a code when a new booking is confirmed.

The sooner you do that, the better a deal you will get on the mortgage, automatically.

Usually calling the potential renter 1hr beforeI could put a solution to automate and integrate all of this, so we would have automatic filtering of candidates, if he qualifies, he could pick a meeting on your available spots (something similar to what calendly does), and the system could require for the candidate to confirm assistance. 

Follow the terms for providing notice on the old lease in case it automatically kicks to a new one-year lease (rare) or M2M lease (common).

Wholesaling may be just right for you.... but be aware - this is NOT an easy way to automatically raise capital.

Low/lower income doesn't automatically equate to drugs and slum behavior. 

It can take time, as you start to buy and sell with your clients you will automatically start to notice trends.

When a tenant completes an application, their  system automatically emails a 5 question form to  those people they listed as references.
