If we were a GC and had cashflow for 2+ years and positive NOI they would consider a small business loan but outside of that, its challenging getting a business loan for real estate.

Yeah, investing in the U.S. has enough challenges of it own.

The only challenges you haven't mentioned is advertising for roommates, screening them and where to get a lease.

Pretty good from @Nathan Gesner too, BUT not 100% all the time.We know some turnkey companies that do NOT want to own real estate or are very picky about what they keep and sell the rest.It is a challenge making sure they are not selling you the property for MORE than it is worth.What country are you currently working in?

Property owners in Florida have faced significant challenges with squatters unlawfully occupying their properties.

In many cases, it takes a few years to really start seeing any appreciable cash flow, but it is the relationships we make, the learning and overcoming challenges and obstacles every day that is the true rewards in this business.

With $50K—$100K, you could fund a rehab and refinance to free up most of your equity for the next deal.Cons: BRRRR often requires more hands-on involvement, especially managing contractors and timelines, which could be challenging with your demanding job and family obligations.

But if do a BRRRR from far away that's risky too, without a really good and trustworthy team in place and lots of checks and balances (security cameras, someone local to check on your property) and the ARV and refinance aspect can be challenging.  

Consider how your property would do as a LTR and underwrite those numbers (worst, middle and best case).I am very happy with my investment but it has been a lot of work and many challenges managing it from California.

I think the most important part is a willingness to learn and succeed plus just knowing your goals and pushing forward towards them.Each market has its challenges and PDX area is no different.
