After discussing with a local CPA, it looks like I am getting overcomplicated in my attempt to be creative.For the sake of simplicity, and assuming the numbers work, it may make the most sense to just sell my primary residence and purchase this one with a 30-yr note and just take the capital gains hit on the sale of our house (we've been in it for less than 2 years).

I wouldn't attempt to police what they smoke.  

@Scott McQuilkin assuming you’ve explained to him that you only received the one month deposit, you should explain to them that you want to help but ask them to provide proof of payment so you can attempt to track it down with the PM.

I sent written offers to the sister by mail, even hand carried another offer to her residence in an attempt to open a dialogue.

We are inheriting tenants in a two flat set to close on July 3rd.  We were originally told by listing agent that leases were ending at the end of June and we would inherit tenants on a month to month contract.

Columbus Ohio is very much looking like a serious place for me to attempt to invest into in the coming years.

Account Closed - in my opinion, your first real estate investment should always be an attempt to house hack!

I'm lending money from my SDIRA for someone to buy a Fannie Mae foreclosure property.I attempted to give them a screenshot of my SIDRA account with a letter stating that I am loaning the funds for the full purchase price.She was told that that was not good enough, they wanted proof of funds in her name.I'm not giving her the funds prior to closing, so we re-submitted the P&S with my SIDRA or assigns as the purchaser.Nope, they wont accept an "or assigns" contract.So we put me and her on the P&S and I plan on signing a quit claim at closing so she will be the only one purchasing the property.I'm curious how other investors normally handle this situation. 

Hey lesson learned this is my 1 st attempt and will definitely not make such Mistake again.

I will attempt to ask the seller and follow up with the city zoning department before making an offer.
