It was immune to the real estate market crash 10 years ago but at the same time it was "immune" to the market surge of the last few years.

If anyone who buys the home has a weakened immune system or respiratory disease, they could react badly to the residual nasties.If it's isolated to the garage and didn't get into the home, completely gut that area down to the studs and seal it with a high quality sealer.

In 2008, no area (with the exception of Texas), was immune from the crash.

Oakland County will be immuned except the areas I named because of the nicer housing stock and schools.

Not saying you necessarily think that, but want to make the point since most newbies miss it and some investors have actually deluded themselves into thinking they are immune.

To me, The younger crowd with more immunity will stay on in the city post Covid .

LLC’s don’t necessarily mean protection and don’t necessarily mean taxable immunity. 

we are not immune no one is myself included.. 

Mold exposure generally doesn't kill, but will make people sick...In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated conditionLead exposure generally doesn't kill either, it just causes brain damage and other fun things to happen...The signs and symptoms of lead poisoning in children may include: Developmental delayLearning difficultiesIrritabilityLoss of appetiteWeight lossSluggishness and fatigueAbdominal painVomitingConstipationHearing lossBabies who are exposed to lead before birth may experience: Learning difficultiesSlowed growthAlthough children are primarily at risk, lead poisoning is also dangerous for adults.

In Redlands, I got $525/door/month clear on a 6-plex, so it is possible to make a nice return.I prefer MFUs for the economy of scale and the immunity from feast or famine on a SFR at move-out time.
