One year from time of payback or time of loan start date I’m not sure of. 

Breaking it down by room can make the process a lot easier.There are also some great pre-made checklists in Airbnb host groups and forums if you need a starting point.

I myself don't have a lot of appetite for risk which is why I started investing in real estate.

I have started to do some door knocking, and I see what you are saying!  

Starting looking for opportunities last Fall and so far it's been terrible.

You have an excellent jump start- the VA loan is such an amazing tool to get the ball rolling.

New landlord here and I've been forced to start my first eviction.

For your mortgage, a 30-year loan will give you lower monthly payments, which could be ideal while starting out.

I'd also start the marketing process 30-45 days before current tenants move out in most cases - it just seems easier to re-let a place that is currenlty occupied than one that's been sitting empty for a while for some reason. 

You should consult with local property managers and find what the average DOM would be to lease your home and rental rates etc. this would be a good starting point.
