The fact that the current owner hasn't bothered to collect rent is entirely his problem at closing and will come out of the proceeds from the sale.That still leaves the problem of what to do about tenants who are (reportedly) perpetual deadbeats.

In the end, it will have to be a compromise between people's personally rights as it relates to their zoning area, or enacting policies that curtail the perpetuation of homelessness and displacement.

Since it was the owner/president of the HOA who screwed you, tell him you won't sue him if he forgives in writing any back HOA dues, and allows you to re-join the HOA, and he agrees in writing that in perpetuity you or any future owner of your property doesn't have to pay any dues.So, if it's paying HOA dues that is keeping your buyer away, if you make the above deal, it's no longer an issue. 

You can invest in something as passive as our perpetual funds.

Yes the news cycle seems to perpetuate outdated statistics, partially due to political concerns.

Find an investment that yields around 45% annually in perpetuity  and you'll be set.Now finding an investment that yields 46% sounds tricky and risky.

It's also worth noting that we have teams of engineers working on our perpetual flood problem and every time we have a monster flood like this, they have new data to work with.

If your tax preparer knowingly signs off on it, they perpetuate fraud, too.

My 'cash-flow' is up (but taxed  as interest🥺), 'perpetual' and hassle-free,  but eventually I'll have to manage the waterfalls and tax situation when the balloons pay out.  

However, like the alchemists in search of a formula for turning lead into gold and the inventors searching for a perpetual motion machine....hope springs eternal.
