LCC as a basic pass through and limited partnerships depending on equity arrangements and profit share of the parties add that extra level of flexibility and not needing to split potential individual partner costs or liabilities.  

Of course I'd choose a place closer to a train station in a larger city but, I'm not looking to make insane profits.

The increases are not strictly about creating more profit for a Landlord, but rather more often than not, they are necessary to keep a property in good condition (including good financial condition), meet safety standards, and ensure a comfortable living environment. 

We want to get into MF (2-3units to start) doing BRRR... and rent out for Mid term rentals.We see a house that meets our buy box, and our investment goals are;- $300 gross profit cash flow per month- 30% equity + with forced appreciation after rehab- Refi (if rates come lower!)

This creates two loan payments ($100,000 of equity and $300,000 on the new mortgage).Key NumbersHome Equity Loan Interest Rate: 6%Mortgage Interest Rate: 7%Rental Income: $3,000 per monthExpenses (management, taxes, insurance, maintenance): $800 per monthIncome and ExpensesMonthly Rental Income: $3,000Monthly Expenses: $800Monthly Mortgage Payment: $2,000ExplanationThe investor earns $3,000 in rent each month.They pay $2,000 on the investment property mortgage and $800 on other expenses.This leaves $200 profit each month or $2,400 per year.However, you have to pay $6,000 interest on the equity borrowed.This leaves you with an annual loss of $3,600.This example shows that while the rental property generates positive monthly income, the interest cost of borrowing the initial $100,000 results in an overall annual loss.

Investors buy, rent, and sell real estate to make a profit. 

You made a profit, which is awesome. 

Usually those who caution offer cautionary tales because they learned first hand the difficulties in growing a scalable and PROFITABLE portfolio this way.

If you put that in terms of percentages for a moment - that is $120/$300 = 40% of your net profit going to the property manager.Often property management charges the first month's rent as a fee to place a tenant.
