So may any seller.Using WCs can be spotted easily in an offer, you may have to justify what may not be customary.

It may make it harder for others to know who owns the door, but that too can be exposed easily by a judge, I just never had to hide out in business.

They are trying to bully you out of the deal, appraisal won't get completed and the fannie agent can filter the deal to another client.Have you had direct contact with the fannie agent?  

Search for table B25004, then you can filter by state and geography.  

If all this is well, (no pun intended :0) ) a water filter coming in from the well to the house would be helpful to capture some of the iron or other minerals before they enter your house plumbing system.Hope it works out good!

It doesn't look like that one could be easily fixed and it also doesn't look very secure (even with a lock).  

Box fee and etc - which could easily bump up to $2000 a year.

If your neighborhood can support $200k condos, you can house hack this into a nice profit a few years down the road.The scenario I'm proposing:Purchase 285kRehab to HGTV level property 45k (total: 330k)Sell other condo for 220k - 15k closing costs = 205 (125k)Refi 4k (129k)Assuming value is still 180k (not HGTV level rehab) you could mortgage 160k fairly easily.  

They cannot copy it (well, not easily) and if they move out, you can deactivate their card.

I do think you're getting discouraged too easily though.
