There are some multi-unit properties that are non-conforming houses. 

I'll PM you contact info for our conventional conforming lender.

Doing the minor conversion to conform to legal standards, permits, and plans, minimal construction ran me $6K.

Including the air quotes because zoning hasn't given their final blessing that it's legally conforming.

Only listen to the Chicago responses on this one because we have a large number of non-conforming units.

@Jose D.Our conforming lender used 75% of lease amounts for properties with less than two years history or a letter from us stating expected rents if we didn't have a tenant placed yet.

You have to be in conformity with these before you worry about building codes.

You can mitigate the risks with additional insurance through an umbrella policyMeanwhile, owning the property under your own name allows you to tap into better rates in conforming loans, being able to go to court yourself (assuming you choose to) just to name a couple for exampleGetting a loan under a LLC will still require you to personally guarantee it, and it will be a commercial loan.

@Tiago RodriguesFor a conforming residential loan, there is a minimum of holding the mortgage "effectively" for 6 months/payments.For what you are asking, you are looking for a hard money loan. 

As mentioned above, you will need 2 years tax returns that show enough income to qualify for your typical Fannie May/ Freddy Mac conforming home loan.
