. ($50K sales price, 5K lost rent, 5K in commissions and closing costs)Account Closed has a good option.

Not a super-helpful answer I know, but the options are pretty vast!

Any option in the middle of these two is when trouble mostly happens.

Hey Maungmaung,You can definitely ask for the rent rolls for the seller and after you're under contract and during option period you can ask the listing agent for copies of the lease agreements.

We give them two options for screening. they can either provide documentation that they are traveling for their job or they can pay for tenant screening.

So, I have an option to buy my brother's house and I would buy it subject to.

Of your two options, I like some version of #1......

One has a 4/2 upstairs and an ADU (2/1) in the basement, but they are not separately metered and doing so is not an option (also, yard is not divided). 

I recommend connecting with a great lender like @Zack Karp to discuss your options as a house hacker.

My other option would be to do a 75% LTV at 7.5% interest, but I would have to come up with $20,000 to pay off my HELOC or carry the balance on my HELOC and pay interest on that as well.
