You have to do some effort and think, analyse, and justify any action you take before blindly taking action.

Keep up the effort and put your foot on the gas, right now.

Being occupied makes it much more difficult to schedule showings or opens; tenants may undermine your efforts with their commentary; many people have a hard time seeing through the clutter and ignoring a lack of cleanliness on the part of your tenant.

Now that the market has cooled off a bit, people are taking a step back to reevaluate, and this massive lull is a great opportunity for people who know what they are doing, know their markets, and know how to make the cash to genuinely swoop in, and capture so many dollars that are being passed up on by so many investors.

You have to make a good-faith effort to find a replacement. 

With a little bit of effort we are now on Booking.com, Marriot Homes and Villas, JetBlue, Allegiant, and more. 

Many inexperienced OOS investors get lured into buying properties in D class areas because the cashflow looks great on paper, and then they get seriously burned when they discover that no PM will put in the significant effort it takes to correctly manage a property in a D area for such little return...then, they're stuck with a property nobody will manage correctly, that is a massive headache & liability, that nobody wants to rent, and that nobody wants to buy... don't fall into that trap!

Most likely they are also in a similar boat as you and you could perhaps workout a scenario where you pool your capital/efforts together to work on your first deal. 

I have been working on my google/Zillow/Facebook pages to increase my inbound leads but I definitely put more effort and money into outbound lead sources.

. $340 - $315k = $25k which is too lean for the effort and risk.
