I’m just trying to get a sense of how common this issue has become and how other STR hosts in urban areas are handling it.

It makes no sense to me that you would need to advertise nationally.

Your post also makes more sense if you are 38.

It makes no sense.

It all comes down to your goals and if it makes financial sense as to which direction to go

I’m not opposed to putting more down to increase cash flow also (COC return suffers of course and there’s an opportunity cost to having that trapped equity but it can make sense in certain scenarios). 

If it’s worked out well so far being a landlord and you see opportunities to raise rents then holding on to the property might make sense.

If you are listing it online, aren't you just in a sense just "listing it on market"? 

Okay, that makes sense.

So won't tend to find as many oppotunities that work to maximize equity gained like single family homes.For single family homes you'll want to stick to neighborhoods under about $225k ARV in order to have rent/price ratios that make sense on the backend for holding as a BRRRR.
