My family is very frugal and minimalist, so other than food and baby stuff and a monthly public transportation ticket, 10 dollers a month for cell phone,  we have no expenses.So what do i do with all my income?

The average time to flip a home is 6 months --again averages, but with a solid network and referral partner you can find incredible deals that are far less price than $250k (like $70 - $90k) and average profit potentials over double from the 20% average example, pending on extra hands provided for your daily research.

And I can understand that with 5 kids some of that first WC payment did need to go to food. 

If rents don't keep up with inflation, owning multiple properties in such locations won't matter because buying power decreases daily.

I'm looking at AirDNA and I don't see those daily rates or Occupancy levels that low. 

. - then they lose thousands:(Here's some useful food for thought (copy & paste):.Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.So, when investing in areas they don’t really know, investors should research the different property Class submarkets.

Cupcake shops sprung up everywhere, the Food Network started their show, Cupcake Wars in 2009 (still on) and then.... a few years later industry consolidation after the run-up.

Quote from @Jake Mercer: I am on BP almost daily, and I can't recall anyone saying, "AirBnB is dead." 

It sounds like you might already be aware of this, but the only time you can put a rental property on a Schedule C is if you provide those "hotel-like hospitality services" that you mentioned, which means things like not just cleaning between guests, but daily cleanings during guest stays, and/or providing them with things like meals or entertainment during their stay. 

Balloons coming due with higher interest rates, China market, China production, Manufacturing production moving back to the US, Worker shortages, Workert pay hikes, Ukraine/Russia food and fertilizer misses, Oil prices increasing due to the OPEC Q1 production curtailments in place, Houthi issues, Panama Canal Water issues, Illegal immigration impact (buy one of those office buildings and rent for $10mm per year for Illegal housing, take advantage) social benefits required, Climate change believe it or not- Buy or sell into that thought process,  US politics, Baby boomers leaving workforce and needing more benefits, Baby Boomers moving from Stocks to Bonds,  etc.I agree things will get worse, but that means more investing opportunities.
