Using VA loans for investment properties can get sticky quickly and once you have mutliple properties it will likely confuse most people...lenders included.1. 

I just have the type of mentality to just do things quick and get results.

Quick question.

Alternatively, you could sell the property for some quick cash and then use that as down payment on another property.Good luck

My first instinct is to go for the 15-year mortgage because I can build equity more quickly and I would avoid being highly-leveraged on my personal residence.

It was not our primary revenue stream but we owned/controlled the adjacent scrap (empty) land and it was a very small (and inexpensive) lot but convenient for 'customers'... but I'd do it again in a heartbeat if I had a similar opportunity.

So I am making some return, but I can liquidate very quickly if needed.

Then I'll contact them with a question or two and see if they respond quickly.

Some want a quick sale, some just absolutely hate realtors.  

If it's in a great location and likely to get snagged up quick maybe you can offer them to start the lease a month sooner and if not then keep looking for another tenant.
