Thus, I'm trying to find a convenient way to accept payments and transfer the payments to pay the mortgage. 

The Program could easily refuse the tenant or the state could say they ran out of money.To the landlords that received rental assistance how long did it take before application was accepted.

We need to accept that and make things happen in spite of where rates are right now.Let me know if you have any other specific questions. 

If you start with some buy and holds, test out some GC's on maintenance / small work then you can start building a relationship with someone and eventually get full blown BRRRR's / Flips going.

The last test I took was 3.5 hours long.

With that said, the buyer can still proceed with the sale if they are comfortable & able to overcome the appraisal gap and/or a solution is worked out financially between buyer and seller to make it feasible.So if appraisal gap is a concernBefore accepting:- Ensure the sales price on the contract is inline with market expectations. 

I'd like to test out offering spots on the property to rent out on a daily basis that are entirely or close to off-grid or primitive.

@Michael Plaks challenge accepted!

@Ryan DaultonYou cannot do this if the offering only accepts accredited investors.There are plenty of offerings available for non accredited investors that also have a lot lower barrier to entry

Significance there is that Fannie and Freddie decided in March of 2022 that they were going to basically eliminate the 10% down option by adding high enough fees that lenders couldn't pass a fees test unless they were going to originate the loan at a loss.
