I would recommend advertising on the usual platforms (FF.com, airbnb.com) with a focus on bringing value to the resident while also being very responsive to any business to business leads that come in.

You're the fish.They often use a mix of fear, threat and urgency to push a target to act.It can be as simple as a 24 hours sale from your favorite shop that requires you to log in to your account first or your boss asking you to wire money right now or he/she/they will lose an important contract that will cost millions.So cybersecurity is important because without that, you might have an incident that can cost a lot of money, impact your reputation and might affect your credit score.

I have heard that it is great for European guests but that's not my target market.

Depending on who you're targeting to rent your MTR, each website has it's benefits.

They spend a ton of money on advertising their product and apparently have none left over to spend on product development.

My company has just grown organically - we've never advertised per se. 

Why not just target $600k buyers in general?  

Is this syndicator hitting targets or not?  

Hi Scott, consider USFR for zero risk cash, earns 5.4% holding 8 week Floating rate note US treasuriesor for mild risk cash, consider BKN - BlackRock's Muni fund, earns 5.6% tax free, which for you would be >9% tax-equivalent yield, and if rates fall, the BKN etf will rise considerably, which though will be capital gains taxable :(, It holds intermediate term Municipals that are all GO, general obligation, so they can always tax us dumb schmuck citizens to pay off the notes instead of defaulting, so low risk but not zero risk for cash. ie (Orange county '90s)Inflation has already resolved, the 3 month trailing core PCE is at 1.5%, well below FEDs 2% target, so they will likely start cutting soon as the 12 month trail falls in line, that's why Powell changed his verbiage so much last Wednesday, and FOMC minutes speak of 150 bp cuts before the end of December as their expectation per their Dot Plots, the only question remaining is consumer spending,(>60% US economy), if falling like McDonalds/Starbucks/Uber saying then unemployment will accelerate and then possible recession, then 10yr yield falls even more, and bonds values would rise like Mike just said above.

You can find different strategies on how to find and reach these folks, such as driving for dollars, targeting mailing lists, networking with Realtors and other wholesalers, and having an online presence, plus paid social media ads, etc.
