I will add my two cents here, as this is something I have been looking at myself.To start with, if you can’t make a deal work with traditional financing then please stay out of the deal until you are Moreno experienced.

Having a high W-2 income is a great asset as it allows you to get traditional financing.Perhaps you are looking for a weekend job/internship to help you learn more about real estate?

2, what is the ROI generally speaking of a condominium apartment.3, are you renting them in a traditional way or using short term rental (Airbnb)?

These buildings are traditionally valued by banks appraisals using the sales comparison method.

The reason I prefer a VA over traditional PM is that I also need someone to manage social media for my RE agent business.

FYI I'm planning to use a traditional loan (ideally), rather than pay 100% cash down, as I've seen some companies require. 

Using my assumptions in the spreadsheet, here is the outcome after the 2nd BRRRR house compared to a traditional method of just paying the 25% down and rehab costs out of pocket for the two homes.Assumptions: Both houses bought at $100k with 25% down, $20k put into each house for rehab, refinanced at 75% of $160k ARV for each house.BRRRR Method End Result: You invested $45k of your own money and bought 2 $100k houses, spent $40k on rehabbing both houses, you're in $195k debt and own 2 houses with an ARV of $320k.Traditional Method End Result: You invested $90k of your own money and bought 2 $100k houses, spent $40k on rehabbing both houses, you're in $150k debt and own 2 houses with an ARV of $320k.Is the whole point of BRRRR to buy 2 houses with less total personal cash invested and more leveraged?

But now that we're leaving for good, we have a choice - traditional long-term rental or furnished medium-term rental?

When you get to the properties that are 3 plus standard diveations from the norm you are starting to get into the territory where the traditional thinking about how to invest starts to break down. 

As I already have traditional investment, I am interested in diversifying and in rental property investment.
