I have dealt with this type of transaction many times.

You can probably find some around DFW in some of the outer cities for around $250,000, so 1031 the ones with the most equity into more properties with chances for more appreciation.One thing I would suggest is not to buy NEW from the big production builders. 

My mum currently lives there, she is 80 and not very well, but you would also become a tenant in common and as such if you had the time you could profit 100% from the transaction, as I need cash urgently and am willing to heavily discount the asset.I am wondering if there is a market out there where someone wants to get a foothold in the London market by buying my part of the property.

I'm sure you're well aware that it is extremely rare for a lead to want to transact immediately.

Were the transfers from the tenant credit card or ACH transactions. 

I know there are hundreds (thousands probably) of lenders out there that offer a DSCR product.

This transaction highlights our ability to identify and execute quick, profitable deals with minimal holding time.

I would confirm by seeing the product then going out and checking comparables in that market that have sold. 

Option D: you are considered a "disqualified person" to your IRA and as such are prohibited from engaging in any transaction in an IRA or receiving any benefits from the IRA (directly or indirectly), therefore I strongly suggest you avoid this option if you wish to stay out of trouble. 

It's a valuable repair and boosts your ARV which is everything when doing a BRRRR.
