In the event of a fire caused by an illegal tenancy, injuries or death sustained by tenants in your building may result in criminal charges against you. 3.

While it is important to be cash flow positive to sustain the business, real wealth in real estate is made in appreciation.

Id be very cautious about buying in the hot markets that have seen big price increases lately. 15-30% annual price increases are not sustainable.

The idea being that FHA wants to know this property is sustainable in the event that you move out. 

The refinance R is difficult with a VA loan due to the extreme LTV, so do not rely on being able to extract that sweat equity but realize it is there regardless   FHA loans have sustainability requirements for triplex and quads that prevents them from being purchased via FHA loan.  

Peoples,I've seen nothing but success, insane appreciation, great cash flow everywhere, but will these trends sustain itself everywhere in the metropolitan areas over the next 1-3 years?

In other words, if you’re think today’s overall homebuying conditions are sustainable (I’ll bet you sell real estate), you’d argue the top of the rankings are simply the nation’s “hottest” markets.

People are paying prices that don't make sense and it's just not sustainable.

I think that’s where you are getting confused.Also, not sure how sustainable/reliable this strategy is - relying on accelerated depreciation in the next deal to offset the gains from the exiting deal.

Focus on building a sustainable income.
