Hi Desiree - I got started years ago when it was easy to buy at house - prior to the market collapse.  

For single tenant NNN the thing that you need to underwrite is the tenant main business operation, if they collapse you lose money with this deal.

Part of the roof collapsed over the kitchen or laundry area I can't see where it came down (roof is shot regardless), fittings from the laundry hookups broke off or burst partially flooding the house, there is mold/mildew from that and the furnace has gone out - woah boy.

Some times missing mortar between the blocks is being reported as a foundation issue, other times everything looks ¨good" but house is about to collapse.

Should the market turn on an appreciation play and sink the price you're hoping to get at sale, you're likely walking into a market that has little liquidity and collapsing values combined, which makes an exit more difficult and extremely stressful.

..So i'm about to close on a 4 unit. its a house hack, but cash flows negative. however the rents are below market and will be raised, and i plan on refeing in a year or two with my va loan to drop my pmi, but with news of a market crash, and economic collapse, and rates expected to hit 6% i kinda want to cancel the deal.

The orangeburg is collapsing, it's only a matter of time.  

Even for multifamily investors, current cap rates are elusive and many will go bankrupt when the tech bubble will collapse and that interest rates will be raised a few pointsHome ownership does not always make sense; money can also be invested in much more profitable ventures that RE

That floor could have collapsed at anytime.  

About 1/4th of the main roof is gone now because either it burned or has been cut away by quickie contractor who is now shoring it up to make sure it doesn't collapse on the house.
