There are tests you can buy on Amazon, where you can swipe it on the walls to determine residue.

You can get solid cash-flowing single families in the 90-120k price range and duplexes in the 130-180k price range.

Many warranties cover single-family homes or duplexes, but for multifamily properties, you might need a specialized policy.

The only deal I’ve ever walked away from we determined that the entirety of two of the exterior, structural walls were significantly bowing and in the basement below them the foundation had been permanently covered so there was no way to see what it was doing.

Condos are also starting to only accept 20% down with reserves, not a good invest strategy at the moment.I'd recommend you stay in Tampa, Sarasota, buy some SF, duplex that need some lipstick and loving, put a tenant in there, and then get a heloc and repeat.

Quote from @Account Closed: I would say.. can you save the tub and re-glaze and redo the tile on the wall can save you $1,000 or more just on materials and labor..

These properties tend to hold value better and offer stronger appreciation compared to duplexes or small multifamily units.

I'm based on the west side of the Twin Cities and am investing on MN's North Shore (Duluth, Two Harbors, Grand Marais) The house were under contract for is a long-term duplex. 

@Dani Beit-Or  Yes, nationwide/Wall Street backed lenders offer HELOCs on investment properties. 

We're currently deciding whether we'll want to go with a BRRRR vs. turnkey duplexes.
