Just make sure you can support the full mortgage payment even if you are vacant should it come to that.

The lady I spoke with today in support said they literally have thousands of complaints.

Some limited support on a one-off basis would be helpful as well. 

But when that claim can be supported, then there would be no trespass by anyone who uses it. https://www.biggerpockets.com/...As to stealing a relative's house, that too is only your suggestion.   

First, if you have a passion for investing in real estate but don't really want to make it your full-time job, then you should either go to university and get a degree in a field that interests you (having a job makes it much easier to access loans to finance deals) or start working straight away and join university in 3 or so years (many universities have a lot of 'older' student supports and discounts and this way you enter uni with an income). 

My job that is very work intensive and time consuming, many weeks I work 7 days in a row.

I really appreciate the support - I'm going to stick it out.There are some positives, I'm learning a ton AND I'm forced to push harder at my W-2 sales job for more income.

Would the existing building be adequately able to support a partial 3rd floor addition. 

There are companies that will supply coin-operated washers & dryers, service them and split the funds with you.Confused though, you stated you have a 4-plex, but that the laundry area supports 16 total adjacent units.

so much as real, consumer demand.
