Right now, the leases on my properties start in April, June, August and September, and if I went under contract on anything else in 2018, the lease would start in Nov, Dec or Jan. 

It's not that you cant sell in Nov or Dec, but expect longer days on market or slightly lower pricing.

My thoughts are to get them on a 6 month lease in Nov. at $1100/mo, and then start an annual lease In June, whIch Is a more favorable tIme to fInd tenants vs. the wInter In MN.

@Ben Kahle it’s not very innovative, but for assets that size we build a bank of parcel lockers using various sizes of something like this:https://www.mailboxes.com/mobile/products/4c-horizontal-mailbox-10-door-high-unit-37-1/2-inches-double-column-stand-alone-parcel-locker-4-pl5s-front-loading-usps-access/It’s much more affordable than the Amazon Hub and other similar high tech solutions.

Here’s information about an interesting one:“The Dutch city of Eindhoven is to be the first in the world to have habitable homes made by a 3D printer, in an innovation its backers believe will revolutionise the construction industry.Of the first five new houses to be put on the rental market next year, the smallest, with two bedrooms, has already attracted applications from 20 interested families just a week after images were made available.Known as Project Milestone, the development is said by the Dutch construction company Van Wijnen to offer...”https://www.theguardian.com/artanddesign/2018/jun/...

So, some will innovate in ways that were not anticipated.

I have one property that we bought in Nov'15 for $185K, its appraised last year around $315, and I think it might be worth $400K or more.

Pete with Innovative Basement Solutions is very knowledgeable when it comes to foundations and foundation repairs 

So you'll see a lot of repetitive behavior like that since innovation won't be well rewarded.

I am using that money to buy my next property which will be another owner occupied home that I am purchasing with 5% down.There are quite a few innovative strategies that I personally would have never believed would work prior to joining this site and hearing about other people doing them.
