If they break the lease, is it legal to keep the deposit in Oregon?

I am wrapping up my flip and was wondering what type of payment documentation I will need for both legal and tax protection.The project involved a GC, electrician, plumber, and granite vendor.Do I need to get waivers from all these guys?

Looks like a house of cards with 100% debt from the first dollar.

Give notice 60 days in advance, noting that the last month's rent was prepaid at move-in.BTW: In Calif, paying first, last, and deposit is not legal;first + lastORfirst + deposit and the deposit can not be more than 2x the rentThat's water over the dam now, but you can start off correctly with your duplex.

With that said, I wouldn't even tell an applicant why they are being rejected if it were for legal reasons.

(Likely resale value on this second duplex is $110)Downside: more financing = more exposure to risk (the loan is 20 yr, first 5 years fixed, then floating.) downside is less cash flow because more goes to debt service.

How much debt are you okay with at 3X rent ?

Does too much debt cause worry for you or your family?

Is this legal?  

Stupid question then - I thought offers to sell were in fact legally binding.
