Moving the rear door over would have helped tremendously but it's not an option with the budget as the exterior has a very dated stucco style and we wouldn't be able to match color/texture and keep it in budget.So I'm looking for ways to define the open space directly opposite the kitchen.

I think your friend needs to cool his jets. 

I asked him about that and he said that whoever comes in to texture and paint will cover most of that up with the texture. 

Very busy Airport & there is quite a bit of jet noise.

You will survive. good underwriter looking at your tax returns will see you own the debt and the asset.. probably gets bounced.. this is what HML did pre 08 all of our loans went to buy and hold folks and we did rate and term refi.. but we were a true third party lender .. its was a great gig while it lasted my average turn on my loans was 92 days.. and the buyers not only had no money in the deal they got refi proceeds usually 5 to 8k a house and they would do 4 and a time.. now they were suppose to take the refi proceeds and put them in their reserve account.. but alas the reserve account ended up having Jets skis in them instead maybe a new car.. or that trip they wanted to take.. etc etc.. anything but where it was suppose to go.. 

That and owning his own jet allows him more flexibility and maximizes him more time to spend with his family. 

For me, it's usually around $12-15 per SF for a mid range cosmetic rehab, but usually that can be cut some here and there like painting wood paneling in a room instead of tearing it out, texturing, then painting, just as an example. 

It would remove the different texture and character that was part of the design. 

We all want to buy a $20M house, private jet, be able to afford houses in the most desirable locations on the planet.

Like reading how a jet engine works.
