In the OFF-chance (not as common), you're looking to get into a DSCR loan...there are ways to get no origination or processing fee by originating your own loan (yes this is possible and you can do it in 39 states without a license).

While it might feel like an extra charge to tenants, these packages often provide value that indirectly benefits the property owner as well—like reduced maintenance calls or ensuring the property is better protected.In my experience managing a large portfolio of properties, these fees are becoming more common due to the thin margins in property management.

Another common practice for nationally sparse datasets such as tax data is aggregation.

And with much more in commonality with starting and running say a restaurant. 

And I know that a refinance would be the best, and most common, way to go. 

Personal guarantees are EXTREMELY common.

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.

Is it a common issue for beginners to get a PM on board with only 1 property to manage to start?

in a vast interview process with many steps before allowing someone to move in. a new roomie is an everyone-decision, not a landlord-only decision; if you're expecting people to co-exist in a space together (for longer than just a few months), you have to make sure they all have some things in common, or at minimum have the right expectations in terms of cleanliness and routine habits.someone working the night shift and someone else having a 5am rise-time, or someone who works from home in a call-center job is not going to jive well for example. and someone who doesnt handle conflict well is not going to jive with someone who is brutally honest and up front about issues. happy to go into more deets on how we do things if it will help. this can certainly be lucrative in terms of cash flow, but there are huge mud puddles i have stepped in over the years which i have had to learn to navigate.
