More importantly they’ll keep you on the right side of fair housing and they may even pay for themselves by charging more rent than you would or not asking so much it stays empty for an extra month. 

If you don’t have a dedt service rate issue than you could get the extra money and just hold it in cash or invest it and us that money to pay down the extra.

We converted property to 2 legal units which brought in an extra $1200/ month in rental income and is compliant.

So, definitely seems to be worth the few dollars extra cost vs. a wax ring.

Thank you for the extra thoughts to consider and advice – really do appreciate it and trying to take in as much info as I can right now!

And even if you don't say it is $50/mo, does paying an extra $10-15k or more to avoid that worth it when that cash can bring in more cash flow and equity gain from other properties or investments?

As far as appliances and “extras”, we’ve really scaled back over time.

After remodel They sell for only $3.8m, you get your $600k back plus $600k (much bigger than your assignment fee) and your friend/seller gets and extra $600k in their pocket making you buddies for life.

That could mean extra capital outlay to attract a tenant. 

And yes, $1 a gallon more is just x more, but at what point does that extra dollar become significant. $2 to $3, $3 to $4, $4-$5 etc, eventually it matters.
