<prompt> Human: So right now I own one house and make about 500 dollars profit a month from renting it out. If I did not live inside it, I would make 1500 profit and if it was paid off I could make up to 3000 in rent from it. Rather than contribute to my 401k, I am aggressively trying to pay down the principle of this house and set myself up to buy another house. Ultimately I would like to have 4-5 paid off houses and hire a property management company to manage them in my old age while I collect a check from them each month. Where is the flaw in my plan? I always see people here going on and on about 401k this, 401k that, but Im 27 and who knows if the USD will be worth jack shit in 30 years? People will always need somewhere to live regardless of what a dollar is worth. My employer matches me and everything so I dont wanna waste my 401k option if Im totally missing something here  <response>: 500 dollars profit a month from renting it outHow much is your monthly maintenance reserve?Rather than contribute to my 401k, I am aggressively trying to pay down the principle Id diversify instead, and do both. Leveraged real estate can turn against you pretty quickly, as millions of people found out in most recently 2008-09. I always see people here going on and on about 401k thisYeah, because we dont like dealing with deadbeat tenants and 3AM plumbing issues. A 401k is a passive investment. Being a landlord is a job. who knows if the USD will be worth jack shit in 30 yearsIn such a zombie apocalypse, your rental houses wont be worth anything either. In any case, we dont invest our 401ks in cash. people will always need somewhere to liveThey will always also need a currency to buy or rent that place with.
