Replacing whatever is in the worst condition is likely to give you the most bang for your buck.

In 2021,I was doing a backdoor IRA for the first time and incorrectly did a re-characterization for $6000 instead of conversion,I realized the mistake and corrected if after few days, in the mean time the value has gone down to $5779,I did not have any gains, now i got a 1099-R for my Roth IRA for the incorrect conversion?

Have a second full bath, even though it was in the basement, came in handy more than once.Here's the mistakes I made1) I included utilities for ease of payment.

First I found an awesome realtor who put up with all of my rookie questions, mistakes, and ignorance.

If you are actually stupid, then owning a business can be a big mistake.

Property owners should expect the worst and plan for it, ensuring the property is as irresponsible-guest proof as possible.

Worst case, I don't think it would be anything drastically different.I will say, when a friend asks for my help moving, how available I am depends on what floor they live on ;)

I agree with @Scott Rankin, you rather plan a base case, worst case and best case scenarios. 

I would go and talk to an attorney who deals in real estate first and see what the 'worst case' scenario would be and how much it would cost.

I had a discussion with a land bank official a few years ago who explained to me that out of the thousands of tax-delinquent houses foreclosed by the county and sold at auction every year, only the ones that no one bid on are transferred to the landbank... it means you really get the worst of the worst... + there's a trick, the LB will sell it to you for a low price... in exchange of your signature on a development agreement leaving you with a 6 months to 1 year to do extensive (and expensive) repairs to bring to properties up to code.
