And at the moment, I am looking to refinance the package of houses, so we can grow wider. 

The big trick is to package the deal in a way that is easy to understand. 

A couple of them can work remotely and just travel the world while making 300 to 500K/year. 

I always create a new tenant/relationship package.

Many of us that live around here travel back and forth over the stateline on a daily basis for work, family, shopping, doctors, anything. 

Simple, use a free property management application with a good accounting package.

More residential units are being built or rehabbed left and right: http://www.crainsdetroit.com/article/20180125/news...https://detroit.curbed.com/2018/1/26/16934714/cass...https://detroit.curbed.com/2018/1/11/16871194/stat...http://www.crainsdetroit.com/article/20170526/NEWS...Businesses have been moving back at a consistent clip: https://www.freep.com/story/money/business/2017/10...https://www.freep.com/story/money/business/michiga...https://www.freep.com/story/money/2017/08/18/linke...Detroit has been named by multiple sources as a top tourist destination in 2018: https://www.nytimes.com/2017/11/20/travel/detroit-...https://www.freep.com/story/travel/michigan/2017/1...Not to mention the fact that every major sports team has moved back into the city, and I won't even begin to link out all of the new restaurants, bars, and retail that have popped up over the last 3 years.We still have our hardships, which people have mentioned.

Hard Money Lenders offer a broad range of lending packages. 

,Because of the "volume game" thing I mentioned above, it's not crazy (when you know a refinance appraisal is in your near future) to be hitting up open houses of your future comps, and getting disclosure packages from listing agents ("Hi Mr Listing Agent, I'm thinking of making an offer, but don't have an agent, and also don't want to waste your time... will you please send me the disclosures?")

I'm just a traveler who has been living abroad for two years.
