I am not familiar with amending in Turbotax, but one thing to note is on the timeline for filing amends (you have some time still, but also good to be aware): Generally, to claim a refund, you must file an amended return within 3 years after the date you filed your original return or 2 years after the date you paid the tax, whichever is later.

After reading the new law I do think the original investor will have the opportunity to purchase the property at the high bid amount. 

Run a full background check to see their credit score, prior evictions and criminal record.

I was originally looking for a 75% loan to value.

If you are managing the property yourself, then yes, meeting the tenants is crucial, as a credit score and background check can only say so much about a person.

So, obviously a good score is accepted, but also no score gives me no reason to disqualify someone.

I believe I can demonstrate that the property was originally used as a two-unit dwelling, which could strengthen my case.I want to ensure this deal is still viable and that securing the proper permits is realistic, as my financial projections are based on this being a multifamily property.

Also remember that no credit score typically can not be held against someone as it can be a sign of a form of discrimination, depending on the reason.This is one where you should ask a legal expert if you risk violating any fair housing laws by doing this. 

Ok buckle up if these assumptions are good:Over the years I have seen a lot of things go wrong and very few right when someone took a primary residence and made it into a rent home, having no experience and the property is not something you would buy originally as a rental property.
