WIth that said "passive" is relative lol. 

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

Seems like relative perspective.

We are only allowed to screen non-tenant applicants for criminal and rental history, nothing financially related. 

Nice try, but this time does not count.In order to meet 750 hours, your wife will need one of the below:- do something else real estate related, like wholesaling or realtor- actively work on expanding your rental portfolio - have an extensive DIY rehab, like a month-long full-time rehab (and then she might need another kind of rehab)- a calamity such as multiple properties damaged in a storm where she will have to deal with insurers and contractors- something else out of the ordinaryAgain - if all you have is 9 single-family properties with stable tenants and typical occasional maintenance - you don't have enough work to collect 750 hours.

In our still relatively limited experience, seller financiers are usually looking to get a higher asking price in exchange for the favor of the private loan. 

Common deductible expenses include mortgage interest, property management fees, repairs, and even travel expenses related to property management.

I'm relatively new to this and am grateful for any advice from the forum. 

Costs will seem high relative to the loan amount on these smaller loans, $5-6k in lender fees isn't uncommon. 

When I first arrived and invested on the Pacific Coast in 2018 it was still relatively unknown to investors and vacation rental investors.
