view=qvI then used rentometer and Zillow to try and get an estimate of the rent I could receive for the property.

They might not pay STR rental rates (ie they wont) but they will pay more then typically long term leases for flexibility on lease terms etc. 

If you were to self-manage one property like this like a hawk then slowly add another and another, ideally down the street from where you live, doing all the maintenance and repairs yourself in order to avoid losing money, then that could make sense. 

I was overly confident, and then the market changed. 

If the property is in NV then you may be a bit limited in choices as they have stricter licensing requirements than most states.

Sales volume in the GNO area typically peaks in June, and then demand begins to drop.

So...maybe leverage the land and the home then rent out? 

I actually did get someone, but then they tried to hustle us with a wayyy lower price when he went to pay

Let them live in it and pay me a rent for a while, And then, offer to sell it back to them in 5 years at $1,000,000.   

When run like a business from the beginning, choosing the right house at the right price and furnishing correctly, then adding the right amenities according to your market, you will do just fine.
