Quote from @Jimmy Chao: I am weighing some options to help my younger brother buying his first primary with a fixer.

However, an easier option would be to use a bridge loan to help with acquisition and rehab financing if the property needs some work.

@Nate MarroquinYou're in a great position to house hack before your income increases, and you have multiple financing options to make it work.

There are tons of options out there. 

Great option for residential and mixed-use real estate investors! 

With the duplex, you can do both rental options.  

Obviously the numbers and location would determine which is the best option for me but these would be my preferred methods. 

If they don't pay willingly, what are my options? 

@Cole Starin sometimes it makes sense to sell the WORST property in your portfolio.Another option is why do a LOC on the duplex, when you could just do a $100k cashout refi to pay off all your debt AND keep the property?

But I would remain open to long-term rental as an option as this seems like a more stable option in terms of income, again this may be my inexperience talking.However, I have always  been somewhat risk averse and investing in real estate is always a big venture, in my opinion/experience, in terms of capital.
