Do you have a list of recommended lenders?

If its not someone you know the lender will dictate the terms.

They want to  review all course content, they want copies of all articles and written materials you have written (can you imagine handing over 20,000+ posts?

FHA is easier to qualify for and allows for higher debt to income.If you have not spoken to your lender already, you should also just look into the HomeStyle Renovation loan.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Yes, I'm a lender, but we have an arm that's been investing for close to 20 years now.

What I think you'll need to find out from lenders/banks/credit unions is how much historical timeline they'll need to review to support the valuation/income.

You got some solid advice above check with your lender and get in contact with an attorney like @Bob Floss II who can help setup the OA.Assuming there is no pushback from your lender, you should be able to do a quit claim deed to retitle. 

You can also search Google and read reviews.

I found the son on Facebook and sent a quick intro giving my condolences, expressed my interest in purchasing the property, and provided my phone # in case he decides to follow up.I'm in the process of preapproval with a couple lenders, and have reached out to a couple realtors in my area to see which may be a good fit.
