I haven’t had any issues here, and I find the courts here to actually be extremely landlord-friendly (even in Boulder which may surprise some people, but I’ve always been treated very well in that court).

This means that if you sell your passive activity, you don’t have to treat its losses as passive losses.

I put in my lease that the property is being delivered free and clear of all vermin and rodents, and if the property needs to be treated for such it will be done at the tenants expense.

How can I keep my emotions in check and treat this like a business?

I am looking to put a new fence around a backyard but should I go with cedar for the long lasting durability or treated pine since it is more cost efficient?  

These are, or should be standards in design and build, that translate to any and all economic markets:1 - Treat the design as the first few times (changes) you will build, and pay for, the house.2 - Treat the design as a system, made up of a series of interacting systems.3 - Understand that design is a series of decisions, with each decision impacting more than just the immediate decision you are making. 

From the lenders perspective, this would be treated as a "gift" from them to their daughter who will be the person taking out the loan without a co-borrower, but still adding the client's name to title at closing for the percentage equal to the real estate sold.

Treat DST like the new timeshare lol. 

lol  i would not surprise in the future if state gov. make new law in CA saying that using SSN for housing / rental is an act of racism haha and LL has to treat everyone equally (DEI).In theory it's hundred times safer to rent the place to (illegal) immigrant rather than US citizen that has 800 credit score but just get out from jail.

It's all in how you outline the hurdles to the owner, have a couple prices on costs (that way you're no longer talking subjectively), and make it clear that ANY buyer will have to do this as well while treating the owner with respect and building a relationship.
