Hi Luis, I'm not sure I understand your question.

At or after the auction you need to do a title search and understand what other liens and encumberances might be attached to the property. 

I understand you can write to your lender and request they take it off once you reach 80% equity, and I'm going to do that.

@John Dickerson  A very broad question but in terms of what you legally must provide as a landlord it comes down to how the laws of your state define "habitability" of a rental property. 

I understand where they are coming from and the politics behind it.

Trying to get a better understanding as to what exactly is required in this process.

I understand multifamily will be hard to come by but also recognize the many pros they provide as rentals (and in my case a sort-of house hack).

Can someone point me in the right direction for understanding how a refinance of a home/duplex works?

I’m reaching out to more and more foreign investors - being American/German myself and understanding the predicaments - to bridge the gap in this issue.

I think many professions have a leverage if they decide to become real estate investorsProperty management - as described by DavidAccountant - we understand Profit and loss statement, cash flow statement etcgeneral contractors - they will know estimated costs required to rehab a property.The rule is use your profession to become a real estate investor.If there is a skill that you are not an expert in - pay someone who knows how to do it better.
