@Jacob D AdamczakThere is no one right answer and a lot of other factors beyond just the simple one at hand come into play - age, other savings, goals, time you expect to be with this employer, etc.That company match paired with the tax deduction you get on your own contribution are essentially free and immediate return on investment. 

You depreciate up to your basis regardless of your entity type.If you are a single member LLC, then literally nothing changes on your tax return. 

Find a market you like and BUY something that will provide decent returns and grow organically.

Remember a 1% appreciation in your property is actually multiple times more return for you depending on how much you put down.

If you are looking for 100% financing start to build an army of private investors looking for a return on their money.

In return, I get to live in one of the units for free.

to get the highest return.

I really want to take a loan against my rental building so I can buy more investment properties, but my situation is I don't have tax returns ( new immigrant and this property has only generated income for 6 months), any suggestion on which financial institution can help a case like mine?

Stated income lenders do not take in to consideration tax returns or verify incomeRates are slightly higher but not as high as HML

How'd the return numbers turn out compared to your projections?
