I am betting you didn't put this (or the other ones) home on the market to then become the bank for someone who only has a couple thousand down and no credit instead of selling to a verified buyer, right?

Some other banks will tell you 40% to manage your expectations but if you have a good credit and a the deal makes sense, the down payment shouldn't be above 30%.As to the managing of properties, if you can self-manage out-of-state in the US, there are no reasons as to why you couldn't do it internationally too and some investors do.

Did you pay with a credit card?  

Alternatively you can do the LOC (line of credit) on it so you can retain the home but are definitely subject to today's current rate environment.

Please educate yourself, and not just from an internet forum. 

Some lenders do have minimum credit scores to access these loan types, but it is the exact same qualifications for income and assets as non renovation loans. 

We talked to our accountant and she was recommending individual LLC's as well as individual checking accounts/credit cards etc..

This can result in significant financial loss and damage to your credit score.

I am currently looking for a small local bank or credit union that issues lines of credit collateralized with investment property.

Your credit will drop if you don't use credit.
