@James HardieMetro Detroit (my rental portfolio is here)Purchase: $80k-$130kRent: $1200-$1500ROI: 10-14%Cash flow: $250-$350/doorAppreciation: Double digit (for past 10 years, will gladly send data)Location: C+, B- (suburbs and certain markets)We have over a dozen Fortune 500 companies just in Metro Detroit with huge Healthcare, Auto, and mortgage industry National footprints.

They also enable guest digitally signing rental agreements and collecting ID.

We have them sign the contract before hand (online digital signature services are great for this) and they must also deposit the security deposit and first month's rent prior.

I guess we can also put a digital thermostat to the electric baseboard to save on the electric bill.

Definitely have as many of the safety measures as possible.Make sure you have the correct STR insurance with pool coverage.Have in your rules more CYA things like Parents must monitor children under the age of X at all times around the pool etc.Vrbo allows for digital acknowledgement of your rules.

If you can save them I'd get a professional to repaint them and change out any old hardware. 

Then I took a paint swatch to the hardware store (it was a light blue) and asked them to have their computer create one gallon of paint to tint 4 gallons of paint.

Back when i was buying at 9%-12% you could also get double digit CD's.  

It's rare to find any MLS listing where you would cashflow more than a few percents (mid single digit) with 20% down. 

Myself as a broker in Texas gets access to zipform plus which has digital signature feature, in addition to adding or uploading forms and miscellaneous docs and emailing to other parties.
