Honestly one of the biggest issues I see us having is nearly half of what we do is undisclosed or unknown to general public.

The biggest epidemic in the real estate investing world right now for new investors is scaling.

. - Hostfully(seems to be most cheap)- Uplisting(seems to be the most professional)- Hospitable(most friendly UI & the only one I currently have experience with)     Biggest con for me is lacking in ai for messaging which they've denied integrations with developers.

Those are the premier Seattle meetups with true experts in the Seattle market.You popped into a forum, new to the site, asked a question, and then committed the biggest newbie mistake in the book - you backlashed against the sound advice because you know better.

The biggest reason I did this is so I can step in and make the payment if my buyer does not. 

I believe the biggest obstacle you will face is the need to rely on a 3rd party builder for a 4 unit building.

Lots of BS excuses and finger-pointing at their hired out Accounting Team for this.My biggest concern now in terms of this one investment is that they are way over-leveraged and are in a position where they will need to refinance soon which will likely result in negative cashflow with interest rates where they are at.   

You will likely have to borrow through an LLC so just know that is an additional cost up front.The biggest thing, at least in my case, would be finding the multiple deals that work for you, that you can take down at the same time.

Job and population growth are some of the biggest factors for appreciation. 

This will get you experience in remodels and much lower down side than a normal flip because you are literally living in the house (so you know exactly what is going on and 0 travel time) and you are utilizing a low down payment, low rate program like a VA loan.
