Hi Elliot,
So you want to work as a wholesaler --
And buy short term rental(s) using creative financing.
This looks to me like you are interested in the cash flow monthly as your main goal.
You also said that you have not been able to set aside enough money for a down payment yet.
Creative financing might be something you could possibly do.
One of the roadblocks you might come across when looking for a creative financing purchase might be your lack of experience - in that the seller might balk at someone with no experience being relied upon to handle his end of the bargain.
Meaning getting a deal like that might be similar to finding a Needle in a haystack.
And making your money from wholesaling - why not just get a second job, maybe from a temporary service, until you get enough money saved up to buy what you want to buy.
And do not forget that you will need cash reserves for times when business is rough, and for things such as replacements like a water heater, which can be expensive.
Join a local real estate investment club or two look online for them,
You can make some local friends there and ask your questions of people individually and maybe find somebody who will let you shadow them a little bit from time to time.
Maybe meet up with them a coffee shop or something outside the meeting, and as they say shake a hand and make a friend.
If you make a friend you may have a much nicer time learning.
Just my 2 cents.
