But, the City uses the opportunity to extract everything they can out of you.FWIW, I have another property that I purchased intending to do another SLSD but elected after buying it to just build more units instead of splitting. 

The man's name was the father (then in his early 20's) of the man from whom we bought the house - people of Polish extraction. 

As for any concern about housing taking a dive (@Mary Mitchell) then invest the extra extracted money in something other than RE.  

@Thomas HatleyFrom a quicklook, it seems a lot needs to be done before you can extract the benefits of the qualified opportunity zones.This is something you want to plan beforehand and not after the fact.

Be the project manager and extract as much knowledge as you can from that person. 

I won't be looking to mine or extract natural resources, nor will I be trying to redevelop the land. 

There are still some new projects that can be worthwhile investing in just have to be careful on how many years are planned to extract the value and strength of the operator.

The advantage of buying this way versus a self directed IRA is that you can avoid all the self directed IRA shortcomings such as You cant directly fix up the place or do any improvements yourselfYou or any relative can’t stay in the place (if it’s a vacation rental, it’s nice to stay there plus it lets you know the quirks/updates that could use your attention that you’d never have realized unless you spent the time there)Also if it appreciates say 300k to 600k, to extract the property out of the IRA you must pay tax on the new appreciated price.Am I missing anything here?

Because of this depreciation, it is important to refinance it soon after rehab if you are keeping it as a rental (BRRRR) so that you extract as much of your original investment as possible.Good luck

On the other hand, is this something a buyer can use a tool to extract a lower price?
