What is odd?

I put the odds at 97% an investor does very well, 2% that through no fault of Praxis' the housing market and/or the economy enter a tail-spin due to inept political leadership at the highest levels, and 1% that Brian is the biggest fraud ever to fool me. 

But anyone who considers themselves a GC for hire, it's a bit odd they wouldn't first get their ducks in a row, it's quite easy.If it was me, I wouldn't worry about him not being licensed/insured, I would just make sure to vet him.

NMLS call center said they have no problem with it but it strikes me as odd that the MU4 filing requires you to disclose other 'financial related activity'. 

It is definitely odd.

Will they have trouble making the payments to you while also having enough money to keep up with the maintenance and repairs/ tenant issues/ all the expenses involved with owning the property?

Your current numbers make no sense (600K property at 70% is 180K down and 420K financed, but four 300K properties at 95% is 60K down and 1.14M financed).The odds of finding someone to loan 95% on four investment properties is extremely slim.

@Alexandra Helms Just seem odd to me that US side isn't much of tourist area in winter than the other side.

(Foundation, etc)4) Black mold, asbestos, lead paint, other other costly repairs. 5) It need significant cosmetic repairs where the purchase price just isn't worth it. 6) They may have an odd layout of the rooms. 7) Non-compliant septic.8) Trouble with permits or tenants9) Listing agent has a poor or incorrect listing.

This could mean either spending at least 500 hours actively involved in the property or ensuring your involvement exceeds that of anyone else, such as a property manager.
