If you need an option that isn't as document heavy, a DSCR cash-out might be a viable option if it's an investment property.

If youre wanting to make a cash offer, all I can say is that Ive never seen a competent seller/listing agent accept a cash offer without proof of funds, meaning a bank statement or similar document(s) showing liquid cash for closing.

That would be a allowed but they should be doing more due diligence and requiring a lot more documentation than what an asset based lender would require.

Go where the deal takes you, don't wear blinders, keep your vision open for whatever opportunities present themself, and NEVER invest on hope, facts only, known documented FACTS. 

But now you have a challenge of documenting both your time AND time of everybody else involved with the property.Now, to answer your question - is it possible from out of state?

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Deals that are more parasitic to the US than beneficial.

To address this I took detailed pictures from beginning to end of my most recent flip, documenting that we did a thorough job using quality materials.   

The answer was no they don't generate the mortgage nope they don't research the deed or title, and nope they don't prepare the closing documents so what part do they do ya I'm not sure why you need them either. 

I'd ask for vet documentation for proof pet has received all state required vaccines.
