I figured that would be the reason since non-FHA loans, Shariah compliant or not, are not as monetarily supported as the government backed FHA program.

For home loans, I've seen it range anywhere from 10 years to 20 years.The home loan is generally only available for buying a primary residence, and some require a signed purchase and sale agreement, while others require no documentation at all.Processing can range from just a phone call and express mail check (you get the funds in just a couple of days), to paperwork that has to be signed by you, signed and notarized by a spouse, and signed by the employer, which can take longer.Interest rates can vary and are generally very low (prime plus one is typical), but you are paying the interest to yourself, right back into your retirement account, rather than to a third party (which is why many people take out these loans to pay off high credit card debt).

Oh, and every loan type will require a notary....so if you are living abroad, the embassy or US consulate is likely to be your only options for notarizing your signatures for closing...unless someone attached to you has their notary license.Probably not want you wanted to hear right now but that's the right information to have. 

@Lauren Beech To Chris's point, (assuming the Operating Agreement allowed for it, which they typically would) you'd just want to have a simple one-pager agreement put together memorializing the buy-out, have everyone sign, and you may want to have it notarized.

If not, are there any other investors in town that could give you a rough estimate?

The Texas company could not do anything but print papers and notarize. 

Don't be scared to do a Quiet Title if needed.First I would approach them and see if you could pay them for their time to sign some paperwork your bank needs.Then have them sign a Quit Claim deed and have it notarized. 

I am going to submit the POF letters, along with a personally signed and notarized letter that I write guaranteeing payment.

If I have some doc that needs notarizing he will come to my office and do it.. when i have east coast closings.. they will do all those .. no appointment I just pop in with the docs they do all the notarizing and if its a big package I forward to them first they print them out on their big printer and they are sitting there waiting for me.. 

Typically a small syndication will cost around $10,000 to set up.I have heard people in this forum state that you can just get some documents notarized from your investors, but then you would be breaking securities law.
