Meaning, to buy an investment property with a traditional Fannie/Freddie loan I need 15% or 20% or 25% down.

@Kris L. well, as the home owner you traditionally aren't going to be responsible for a refrigerator, washer, nor dryer. 

Investment loans are always about a point higher than traditional home mortgage.

The good news is rates for those are typically less than traditional purchase finance deals.

Anything I should know before entering this landlord platform?

Add that to the high number of hourly and tip-dependent workers in tourism and restaurants, and the Miami-area ends as the third-most economically exposed cities in the U.S.For the local multifamily market, that may spell trouble.The study, San Francisco-based apartment search platform Apartment List, ranked the Miami metro area of Broward, Miami-Dade and Palm Beach counties just behind Las Vegas and Orlando when it comes to the size of the population most at risk economically from the coronavirus crisis.

We provide safe and affordable housing to citizens who can't afford to purchase homes themselves.Second only to to food, shelter is important as a basic need that no American should live without.This is why I am writing to you to ask for help in the implementation of emergency changes to the Federal Housing and Urban Renewal Section 8 program.As a landlord I propose the following:The qualification for Section 8 should be opened to all unemployed American receiving unemployment benefits.All Landlords who file a IRS Schedule E are eligible to receive benefits based on properties listed on their Schedule E for 2018 or for any 2019 tax return filed.Section 8 will waive the home inspection and Landlord requirements for the participants  in this emergency program and will not remove the traditional application process for those seeking to participate in the Section 8 program.   

What would be a good platform?

.\- FINANCING STRATEGY: list price is $90k, I will be opening up a HELOC on primary residence to get the $18k for the down payment and then hopefully a traditional mortgage for the other 80%

Interest rates are really low so I'd recommend a traditional loan (set it up as a refinance from your parents loan).
