What I have seen is an internal sales team (AE's/Reps who split their time between referral partner development and managing their pipeline) combined with someone solely responsible for digital marketing (social media, SEO, ppc).

Sandwich LO are even better.First and foremost, NEVER combine the two into one contract as the seller.This topic is a seminar unto its own, in order to fully explain what I wrote above, and to understand the why and how. 

I used a combination of Minoan and going direct to vendor to furnish our 4BR/4BA.

Combined that can cost $50k+ which they may not want to pay nor their is the possibility they would not they pass the DD report.Nothing wrong with raising money in this fashion (FB or online ads), many do it and are great sponsors. 

@Michael BertschAs a general rule, we only leave a fireplace functional unless it has a sealed, externally vented, gas insert ... and, even then we may disconnect it.Check with your insurance provider and see how unhappy a functional fireplace in a rental makes them.

You can diversify your house hack inside itself if you combine rental strategies.

The Roi combined for 3 duplexes after repair will have an ROI of 4.47.

B) So you're going to combine unsheltered people and basic homeless?

I was in a similar position a few years ago, but fortunately got married and our combined incomes helped us qualify for a larger house hack.We're on our second one in NOVA, Alexandria to be exact, and instead of rent by the room, we are renting out our walkout basement on Airbnb to monthly guests.That said, we have a number of friends doing well with rent by the room across NOVA, though they're purchasing homes with 5+ rooms or finding homes that can be renovated to include that setup.I'd recommend attending meetups such as the one I cohost, NOVA REI or Cashflow Breakfast Club or any of the others to meet those who are house hacking.

Short term or long term, everything should function!
