difficult to find a reasonable deal by using THE 2% RULE and THE 50% RULE.I concerned I'm missing a lot of potentials deals.How do you filter deals?

And if math makes your brain freeze then that's a concern for you wholesaling as it is 90% math.If you don't know what values are where you are investing then I almost think you need to decline the offer to market them.

What are some pointers on how to assess the property/mobile home?

The main concern you are going to have is with seller financing how is the agent going to get paid.

Is that a silly concern? 

I get bored pretty easily, so I like to reposition when it makes sense...either taking capital gains or working through a 1031.I don't need the cash flow, so control of assets is my primary concern...different than what 99% of "investors" will tell you...In general, there is no better way to control assets than through purchase money mortgages.

As a newer investor the only concern with owning in personal name is when you have an "institutional" mortgage on the property.

Agree with @Michael Hacker, the extra weight might be your biggest concern. 

What about liability concerns from tenants or creditors?

You can even diversify across asset classes - think MF, self-storage, mobile home parks, office space, etc - AND geographic location.One limiting factor though is whether you are accredited or not.
