There are some weekend and evening calls but they don't pay enough to deal with all of the requirements, including going to a staffed FedEx location to mail the package the following day.

I would like to be able to afford my whole mortgage at 100% vacancy in a disaster scenario, which puts me at buying houses less than 200k at the current interest rates including expenses and insurance.

For example, could you scale and have the security of modest cashflow (somewhere between 2-5% after all expenses, including CapEX are accounted for), if you put 30% down? 

My payment (including escrow for insurance, taxes, etc) of $2500 would go to roughly $4500.

However, while we were cleaning up, we treasure hunted out at least $3000 stuff, including $300 cash on the floor, several un-opened Amazon boxes, new-in-box computer/gaming items, hair tool ($300), YouTuber's gadgets, new with tag heated jacket ($220), an unassembled exercise bench ($500 at least), so many new or near new stuff that you can sell.

I feel like this is suchhh a common question for new house hackers, including myself. 

But, a funny thing happened on our way to the Forum: we were able to learn first hand how to manage properties, deal with renters (including the House from Hell and the Renters from Hell on our 3rd property), what to look for in deals, etc. 

Then I thought I could buy the house from my dad for $300,000, which would include the money needed for the rehab instead of doing 2 separate loans.

I would just budget to fix it and include that in my offer price. 

The landlord is "allowing us" to break lease (and handle all the rental ads and showings, of course) but has jacked the rent from $2250 up to $2500.
