Put simply You get much more bang for your buck on multi families VS SF.
Take a 4 family for example: you are getting 4 income streams while paying taxes, insurance on one property. You can safely assume the taxes and insurance will be higher on 4 single families vs one 4 family - well at least in NJ that is true.
Another great thing is with a 4 fam. for example if you have an apt. go vacant for a month or two that is only 25% of your rental income vs a single family that is 100% or say a 2 family one vacancy would be 50% of your income produced from the property. It hurts alot less when it is a smaller % of your income.
Another plus is it is easier to manage having 4 units at one location vs. driving to 4 differnet locations to manage.
Of course multi families do have down sides - but the positive IMO definitely outweigh the negative.
I'd like to end this by saying Single families can be a great investment as well if you get it at the right price and location. And that may be the way to go for your first investment property so you can get some experience and see if you are cut out to be a landlord and manage property.
My first investment was a 4 family with a 5th basement apt. I bought it for a song back in '97 when I was pretty young (24) everyone said I was crazy. I had initially planned on living in the basement apt. but the guy I bought it from who was living there asked if he could continue to rent from me so my plans changed and I stayed at home with Mom for a few years and was able to collect 5 incomes.
This property turned out to be a phenominal investment as it allowed me to bank tons of cash while keeping my monthly expenses very low.I was able to buy my next property pretty quickly.....
That property is my biggest and still today is my cash cow. Rest of my properties are smaller 2 and 3 families.
kind regards,
