Dave foster brought up the point I was going to say will probably sink your deal. 

You want to walk every inch of either side of the home inspecting for soft floors (water damage- particularly tubs and toilets), under sinks (water damage and dry rot), door frames and exterior siding (dry rot) and most importatnly the roof. 

If you see missing cabinets, soft floors, or signs of leaks under sinks, that often points to plumbing or subfloor issues.

Maybe there is a sink or an old laundry hookup/drain that isn't being used where the trap dried up allowing sewer gas to enter.

Instead of sinking excess cash into one property or overpaying down debt, we place smaller amounts across multiple deals, spread risk, and let the portfolio compound without overexposure to any single asset or market.

You have to interpret  what the form is asking. another thing,off the top of my head is if there is water present like a sink, any electricl outlet with in 6FEET have to be GFCI. 1.

The other 5 rooms have to share one bathroom with dual sinks, a tub shower, and toilet.

A few high-impact items to stay on top of are:HVAC: Annual servicing and regular filter changesPlumbing: Check for leaks under sinks and toilets; inspect/flush the water heaterSafety: Test smoke and CO detectors, and check GFCI outletsRoof & Exterior: Quick roof inspection, clean gutters, and check caulking/sidingDryer vents: Clean regularly to reduce fire riskThese basics go a long way in preventing bigger, more expensive issues down the line.

With three or four units, one vacancy or one major repair can sink your year.

Usually hanging from the towel ring near the sink.
