A low price would be important but not too low (so that it raises buyer concerns) and ideally a brand that is well known and liked by MH buyers. 

Heck, I run it and print it out for a seller and include it with my PA as justification to my #'s that I am not just low-balling em but here is the facts, I'm gonna have this n that price coming up. 

I'm planning on quitting soon, moving back home for a little and taking a few months in between my next job to pursue my first investment.My rough idea for an investing strategy is:  long-term, not necessarily looking for high cashflow (just want to start building equity), quality deals > amt. of doors, Class A/B neighborhoods mainly for low vacancy. 

Home prices are very reasonable, Taxes/Insurances are low and they offer more inventory. 

Lastly, I'm never trying to book way in advance (especially during high season), if I am, I am likely priced too low.  

Short answer is as little as possible.The long answer is it depends on the deal.Typically you end up in a subject 2 situation when the current owner has little or no equity in the property, the current advantage of subject 2 properties is that most mortgages are below current market rates.Keep in mind when acquiring a property subject 2, in most instances you are not notifying the current lender of the change in ownership, and most if not all mortgages have a due on sale clause, which is the lender's decision if they want to enforce it or not.I personally like the idea its a great way to get investment properties with low rate loans, that with most likely appreciate in the coming years.

In that case I'd likely sell the ones you lived in and move that money to a high yield savings account or low risk index fund. 

I think your quote is low and it will end up costing more.  

Do you want higher risk and more return or low risk and lower returns?

If a property has a low return on equity, as in low revenue relative to value, it would make more sense to sell because you likely have equity that could be redeployed elsewhere for a better return.
