Something almost always comes up and that helps you be realistic when evaluating deals, securing financing, etc. 

@Elizabeth RossFor properties under 100k you will likely need to use the BRRR method as its difficult to get a 30Y loan on a properties valued under 100k.

Could you advise where investors typically secure financing for similar land purchases?

Secured creditors in order to take the property are to put in a motion to lift the stay.

If you think you might get kicked out then housing security might be worth upping the payment. 

Or even missing out on securing a better deal, higher price, or greater return but did not do so, often due to a lack of negotiation or oversight.

If they don't you personal financial situation plays a bigger part in securing a loan. 

My strategy has been to grow aggressively (by using as little of my own money as possible) to secure good assets, and once stabilized, then work to pay down loans to own them free and clear sooner rather than later. 

I sourced the property off market and secured seller financing, and I also self manage it as an Airbnb host with nothing but 5 star reviews.

If prospects upload ID, pass a quick background check, and maybe upload a pre-approval letter, I think that answers both the security and tire-kicker concerns.
