HELOCs are extremely difficult to get for non-owner occupied properties. 

Customer Service was non-existent.If anyone has a recommendation for a simple email / messenger automation service for AirBnb, I'd appreciate it.        

I plan on focusing on notes, performing at first, and then working my way to non-performing. 

That relationship is now off because of personal, non business, reasons and my new lender is requiring that I get due diligence before.

I am worried mostly about the length of potential vacancies and costs of potential evictions/non-paying tenants.

They do have a yearly membership but I think I'm going to try and attend one meeting (I believe they have a door charge for non-members) and see what they are all about.

Yeah - get ready to evict Dad for non-payment, which is what is coming. 

If you and/or your brother don't want to do that then come up with the 25% and buy it as a non owner occupied duplex/triplex......If you don't have the money.....then someone has to "sacrifice" and move somewhere for a year.

Price sounds like it is good for the area, based on age of house and the fact that any non-family buyer might just tear it down and start over.

If the plan allows for it, Roth 401k funds may be contributed and non-Roth funds may be converted to Roth within the plan.
