Should I mention that perhaps they should explore a title loan, cash advance, or payday loan (I have no clue how those work)?

Compare that to your LOC rate and you'll see it's a nice payday.

He's correct that, unless you automate your systems or hire employees, you'll still need to put hours in to equal a payday.

His/her 'return' would be calculated after the pay-day.

Offer too low, sellers hold out for a bigger payday and I miss out on a marginal deal.

If a person understands the basic math and doesn't mind having some low cost debt (as opposed to high cost consumer debt like credit cards, car/payday loans etc.) you are much better off investing your money elsewhere and paying back the debt over time or at a later opportunity.As much as I like most of Dave Ramsey's material, I think the "live debt free" idea, is extreme and comes at a significant opportunity cost at today's rates of interest.

You still have very good appreciation potential so still could be a good deal if you want to hold out for a bigger payday.  

my biggest pet peeve with my handyman is that he is messy and doesn't clean up well...washed his paint brushes so much in the bath tub in one unit that it clogged the cast iron..to be fair the pipes were on their last months anyways, but now i specify to use the hose outside....most handymen will leave a mess until the last day, and then be pissed when they have to clean it up..it's better to just clean up your little messes every day..definitely let him know he is responsible for cleaning before he leaves every day...also, my handyman likes me to buy all items, as he never has money...this is good bc i am not getting upcharged for his services of going to the store...then again, everytime he needs an extra gallon of paint, or even one little fitting for pex, he calls me while i'm at work and can't do the job until i get him the piece....I WILL NEVER DO THAT AGAIN...for now on, it will be worth it to me to pay a little extra for their services of gathering all materials, and i will get quotes for materials and labor..but that depends on how busy you are i suppose...also i like to specify that they can get paid on Wednesdays, per job they have fully completed...i will not run out there on a friday night bc he needs money and finished a job..going in, they know wednesday is pay day for them for the work that has been completed so far..let me know if you have any questions, as i have worked with a few shady people!!

I don't want my tenants to be stuck in a trap or feel that they need to take out a Pay Day loan to pay me, but I don't want to be paid late. 

You are asking a lender to give you $100k up front and trust that you will make repairs instead of walking away with a $30k payday and dumping the property on them.
