@Ben Gordon - This is not a new issue, nor is it specific to your area. We have always taken the approach of finishing out properties at the top end of the two markets we're in. We've been able to attract strong tenants at high rents that support the improvements made, BUT there aren't any comps for what we do for two reasons:
1. Very few people improve rental properties above the market
2. Those that do make the effort to go above and beyond very rarely sell
What has ended up happening is we've had to argue on appraisals during refinancing and also keeping more cash in the deals than initially planned. We've got one in the works that the appraisal was so low I went back to the bank and they had the appraiser redo the appraisal based on my comments. He made some updates but did not change the price, so now their chief credit officer is stepping in and basically telling him he needs to account for value that he missed. It's very annoying and unfortunate, but we're okay leaving more equity in the deal if that's where things land.
This has resulted in slower growth for us than we'd like, but also much better cashflow. We've also skipped the refi on a couple deals because the effort was not worth the amount we'd be able to get out.
It's also worth considering the macro picture, lending is relatively loose right now and appraisers are fairly reasonable. If we see an economic downturn of any sort, both will tighten up and the scenario's we're seeing will only get worse. As long as you have a plan A, B, and C you'll be fine. If the only way you can work the deals is with a strong appraisal and cashout refi, then you'll eventually get put in a bind.
