I believe home equity loans have a fixed interest rate and a HELOC has a variable rate Also are there closing costs involved? 

On a high level,  I guess my question is when purchasing MFH, what geographical and demographic variables do you need to keep an eye on?

My broker is charging me less than 4% right now - but it is variable.2)  The markets are hot everywhere right now.  

I was curious if anyone is even considering using variable rate debt now to fund acquisitions.

Mine is to create passive income, as I too am in sales, and have a variable income. 

There are lot of variables and not all lenders will accommodate.Cheers!

This seems to be one of the hardest concepts to grasp due to the rules that create confusion with moving variables around such as rent income, expenses, vacancy, repairs, and capital expenditures. 

But there are so many unknown variables here.

Another thing to consider - What my parents paid $70,000 for in 1978, my son paid $160,000 for in 2017 (well his is smaller) BUT there are a couple of other differences - My parents - bought the home with a mortgage at the going rate of interest 14% - payment - $829My son - put in about 20,000 - refinanced the place at $180,000 (appraised value $280,000)   interest 4% payment $859It's hard to compare the same neighborhood 30-40 years later without comparing all variables - BUT do I think we add to the issue - for most of us I would say no - what we do increases the value to everyones home.

Pros: -Interest only payments for 15 years -Can pay down the principal if you wish on your own timeline in that 15 years, and leave it open for future use if you want if you want-Whatever available funds are available also function as a rainy day or emergency fund if you see a need (but will need to get paid back, obviously)Cons: -Most are variable rate and fluctuate with the whims of the Fed; standard seems to be around a point above prime (could be better and/or fixed if you shop around)-For future lending, they can hammer your DTI ratio because lenders could base your potential monthly payment on a worst case scenario high interest rate (I was told 10%).
