Quote from @Gregory Banks: I would hire a structural engineer. $1,000 inspection could save you tens of thousands.

Now purchasing a home with cash is always good b/c obviously cash is king but also I think the part you might've missed is that, the money your utilizing on these home's won't actually be yours, but the banks or whatever institution you used to fix the home or make its value worth more.

You can talk to the bank about a loan; however, my bet is they will want some form of contract and scope of work and will only pay him at set milestones.

2) Are you pre-approved and have the down payment in your bank account?

In order to have checkbook control, the IRA account will need to be at a trust company that will allow the IRA to invest in an LLC (where you will be the manager and your IRA will be member - an as manager you will have checkbook access to the LLC bank account).

Does she or I call the bank to see if it's possible to transfer?

If you can get a better deal on the home due to age its a fine and if you need financing banks do not judge year built. 

Hey Chris, a few thoughts here.Considering that office is not attached to the house, I wouldn’t add any footage to the total home square footage; however, you could advertise that office space and amount of footage and amenities in your remarks.If you’re a Realtor or are using one for the sale, your local MLS may have fields dedicated to additional footage for other buildings on the property, such as ADU’s.The other point is that typically, perhaps depending upon location, a space needs to have heating to count in the square footage, which this office doesn’t have if I understand correctly.Consider contacting an appraiser to inquire about how they would handle this space on an appraisal, or a Realtor.
