Don't expect rates to come down. 

Quote from @Brad Kremer: Hi everyone,I own a cash-flowing duplex in Austin, TX, that I bought 8 years ago when rates were considerably lower than they are today.

Quote from @Kaushik Sarkar: I’m exploring strategies to scale my real estate portfolio given the current mortgage rate Not sure much makes sense at 11%...Ouch....tough enough at 7.5%   Might have to put more than 20% down to finance....maybe 30% in North Texas.   

The rate will also be high. 

And you are looking at an interest rate around 7% instead of over 10%. 

They are short term loans, usually 6-12 months, high rate, interest only payments. 

Fortunately at my rate they have some cash flow and good appreciation.The rates make it rare that the brrrr is the best option available.  

Some people only want 10-20% of their outstanding lines/debt balances available while the other 80-90% to be in fixed rate notes.

Last year, I purchased a SFH under market at 7.65% interest rate and did some rehab to up the value.

@Chinku Chinku the rich get rich by making their money work for them.They borrow at one rate, to invest in something that returns a higher rate - they profit on the difference.Only you can evaluate your risk tolerence though.
