There is a very supportive investor network in the Madison area.

Plenty of people try to get around these rules by creating companies with Thai majority directors or using usufructs to lease homes long term. 

You will definitely want to get residents on the new lease agreements so that you can manage the park in a professional manner and enforce rules.

@Patrick Sears  If I'm understanding everything correctly "1/2 the note for 1/2 the payments" and the others are just rules of thumb for pricing a partial. 

It meets the 50% rule.

However, rules don't permit providing personal guarantee therefore you must use non-recourse financing, typically need 40% down.

Make sure you can add units that the sewer line can support.

The golden rule states that "you should love your neighbor as yourself"(I know that it is very easy to say and repeat, but taking action is what we should all strive to do and act upon because anything is better than nothing).

It's time to start once you have saved enough to comfortably put 20% down, have enough reserves that you can handle a major repair + 6 months house payment, have researched local landlord laws and rules, have a good idea about what paperwork you will need and have it ready (lease, move-in checklist, background check, etc...), and you've done your research so you know what a good deal looks like.Then the hardest part!

Every mls has different rules and regulations but in every case that I know about you can only gain access as a real estate agent.
