That seems to be pretty rare these days but every loan is a little bit different and there is no way to know without reading the documents.

As a side note it is generally rare to find someone who is great at finding deals but also doesn't want to put any money in them to have a greater equity share, they may well be a beginner with little more experience than yourself and at that point you really have to ask yourself what you are paying for. 

That combined with the notion that the mortgage is likely to be assumable is what makes me ponder the idea of stepping into that seat to try negotiating an assumption and reduction at the same time.

However we'll typically draw our rectangle/shape/whatever around the area we're covering, or pick specific zip codes, checkmark combined LTV 0-50% (sometime include unknown if small enough area), last mortgage opened 7+yrs and/or lived in the home 10+yrs. 

But building a new one is rarely cheaper than buying existing.

If this is a short sale, you can very RARELY assign a contract. 

@Jordan PrattAnother idea is if you have the cash in hand, maybe could combine the strategies.Buy a mobile home cash.Improve the property at whatever pace you desire.Bring in roommates and pay yourself back over time.Either keep the property if it’s cash flowing or If you want to sell, do seller financing when you are ready to move on to the next property.There are a million options in real estate and you can mix and match to make something fit your goals and situation.

.- The "best case" timing rarely happens. 

Their best buyers get their best deals way before you do.Given all that, I still sign up for every wholesaler's buyers list I come across at meetups or on facebook....hoping for one of those rare good deals that do turn up.

Looking to get involved in building a small residential portfolio to eventually combine in an aggregate sale for one small apartment building.
