You're the buyer at this point, until the contract is assigned.3. 

Consider this scenario:- A tenant calls at midnight because the heater stopped working.- You need to find a new tenant when someone unexpectedly moves out.- The bathroom sink is leaking—do you pay a plumber or fix it yourself?

Congrats on this investment @Kai'ler Sato ! 

Purchase price: $240,000 Cash invested: $60,000 purchased this distressed duplex using owner financing for $240K and a $60K hard money loan for renovations.

I don't think it's wise to try this until you have proven experience and a solid partnership agreement.It's OK to scale slowly.

You are definitely going to want to get a lawyer and as soon as possible.This will sound harsh.In your story, you have made a number of very poor decisions about how you purchased and managed this property. 

I'm just new to this world and wonder what someone with some experience would do.

How many views has BiggerPockets had on their content on this stuff?

For instance, the area closest to Disney is actually less saturated and has many homes that can be renovated to a high standard and will book well.A bit further from Disney, in newer communities such as Solara, Windsor at Westside, Windsor Island and others, you can find deals in this market.
