Do not rely on it for legal advice.

A private lender and I are going 50/50 on a down payment, I have cash & my private money partner is using HELOC funds and I am wondering how we can legally go about using our cash ASAP without a 2 month seasoning of funds.

But I see the importance of having things written into legal contract.

Most likely the easiest and least problematic legal way to get rid of the tenant will be cash for keys, but find out first what the tenant's lease says.If it turns out that the tenant has no lease AND has no interest in leaving, you'd best start boning up about eviction law in your area.

Check to make sure wholesaling is legal in your state.Buying a duplex and moving into one side?

So you now need more skin in the game with guarantees of the lease,rental increases,etc. as it affects a larger portion of the building now.No legal advice given.

Do not rely on it for legal advice.

Or do I draw a hard line in the sand and point to the HOA rules drawn out in the Trust, Bylaws, and CC&R's and pursue legal action if he continues to refuse responsibility?

Can someone explain to me all the legal contracts you can put someone under during a wholesaling deal?
