However, you need to be connected to the Internet in order to generate the codes on the erentallock web site.The way this works is that you setup an account with them and provide a master code.

No more than you should become a master electrician, master plumber, HVAC tech,  insurance agent, loan officer, and maybe other licensed people.   

@David RoqueDid you consider doing a master lease on this deal?

I'm in Cuxhaven Germany and reaching out to German and European Bigger Pockets members because I'd like to set up a European Bigger Pockets Master Mind group.One of the purposes of the mastermind is to focus on pooling together resources, be it funding, knowledge or expertise, for all the deals this growing group might offer.

We really stretched ourselves thin. we did not perform our own inspections because we were busy raising finances .. and our agent insisted we use the same company who did the initial inspections to “get a report in our name” .. we went for visual inspection with our agent and found the master bathtub was  upside down — they said there was a chip and seller was fixing the tub.

It could make sense to bring in an investment partner.Another option, since it sounds like it's a handful of smaller properties, is to get a group of people together and divide and conquer the units rather than having one master portfolio with LPs and GPs.Feel free to DM me if you want to discuss strategy; I'm happy to help.

There are multiple ways to master the concept of house hack.

For example, doing the kitchen,paint and floors in the 2 months before moving in and then moving to bathroom renovations or adding a master suite addition while living in the property.Depending on you jurisdiction and capital you can use the value add house hack to even add an adu to increase the density. 

With 30% down your options are thousands of lenders.Why is it unwarrantable- master policy not enough coverage; low occupancy rate; HOA reserves; cannot be rebuilt or repaired; pending lawsuit in the less than 10 year after built for construction defect; flood zone with no flood policy...?

Tenant James (fake name) is in the master.
