I completely agree with @Steve Rozenberg about dedicating time to get educated and planning out the short and long term goals that you and your wife want to achieve.

For example, on an average day your property’s rate will be lower than on the day of an event in which it's located nearby.The expenses related to this property are non deductible.The property that the taxpayer is renting out must be a personal residence such as a house, mobile home, boat, condo or similar property.The 14 day limit does not need to be consecutive.

GOOD - Getting crazy-good response to my web page and CL ads and mailers BAD - Someone wanting to sell their mobile home and I have no clue how to value it.

Since they are mobile and can be moved to any location is there a certain code they need to built to and also is calculating arv and estimates the same and also how do you take into account taxes ?

I do however see people upgrading their primary residence to now include a home gym, dedicated office space and home theater room..

Mobile home parks are great investments. 

There is also a mobile app and web reader - So you can read anytime even if you didn't bring your book or kindle, your phone will sync with the kindle so you can just pick up and keep going. 

If you have never heard of the BRRRR strategy, scan the Bigger Pockets podcasts for an episode dedicated to it. 

Venmo is another mobile optIon but they have a maximum transfer to your bank account.

But I've always been intriqued by mobile home park investing too...owning just the park, not individual homes.
