For the low-interest mortgages, I personally would never pay a cent extra, just let my tenants pay down my mortgages, because I can earn more even on a short term CD than I would paying them down.

Draw the line based on what is the return for each. if it costs and extra $40k to get you $40k price increase it is not worth it, it has to add value to you.

A lot of truth to what you wrote. 

This is not an absolute truth by any means, but a way to filter and have a better shot of those looking to sell/retire.   

I am just giving you the truth.

Asset hunters find unique assets and things others can't see (extra land for an ADU, extra room for another full bath, etc.).

So you're asking a tenant to use a system you have put in place, then when it takes a couple extra days you want to charge the tenant - regardless of the tenant's intent and the fact that they are following the rules you put in place.

This is participation trophy culture and reverse trolling at its finest.I guess from now on, you can only give back pats, hold people's hands on their journey, and encourage them, and not tell them the truth about their questions, investment ideas, or future plans.

A good deal will always be a good deal so it shouldn't stop you from taking advantage of an opportunity but depending on what you're looking to do and where the properties are you may want to budget for an extra month or so when selling on the back end.

Truth is, I think that everyone should start small by buying their own househack, learning the ins and outs of Real Estate, and then progressing to bigger steps moving forward.
