I used to work for Big Brothers Big Sisters in SF and then another social service agency here in Ukiah.

and are there any good property management apps that are mobile and a good interface between owner and PM (as opposed to interfaced between PM & Tenant)?

Interest rate pricing on both is bad; you can't have your cake and eat it too.Many retail banks (places you can have a checking account) only offer one or the other, but not both, limiting the options that consumers will be given, until said consumers reach someone offering the full gamut of Agency mortgage products.One said I can't use HELOC for a downpayment.That particular institution might have that overlay, or that particular loan originator sucks at math.

Hey does anyone have any advice on investing in mobile homes or books, podcasts, webinars that elaborate more on mobile homes.

So you are saying to go to BP (the non mobile site) and you can download (with WI-FI), then listen later?  

Basically as a potential renter if you want to see a property you show up to the house and either by inputting some information on your mobile device or by calling someone ahead of time they will give you the code to the key box.

Bandit signs work, but they generate random calls - you don't know if the caller has equity, a mobile home, etc.  

So call around to some other agencies and ask them if they manage anything else in that area.

I have heard I can buy a mobile home park, with little to nothing down, and seller finance.

The credit reporting agencies have changed how they view multiple inquiries in a short amount of time - as long as the inquiries are the same type.
