I have three different tenants all paying separately for one house. 

I'm kind of inclined not to pay it as if he called us like he has in the past as soon as he noticed the issue we could have taken care of it.Any advice would be appreciated.

If the only cash being pulled out of the house is to pay off the first lien (private lender), is there still a seasoning period?

For brevity's sake, I understand the merit of seller's not paying professionals to negotiate against them and I am a proponent of brokers having greater flexibility and influence on compensation allocated, as it provides all parties greater chance of compromise. 

Job/ income - tells you if they have the ability to pay you.

You usually pay an upfront option fee (around 1% to 5% of the purchase price), and a portion of your monthly rent may go toward the purchase price, helping you build equity over time.Pros: Flexibility: It’s a great way for buyers who might not qualify for a mortgage yet to secure a home while improving their credit or saving for a down payment.

My tenant is not paying rent for last 3 months and I started eviction process.

Can I use rate and term refinance to pay off my hard money principal (including rehab portion) until the 12 month seasoning period until I can cash out?

They pay you $500 per night. 

Honestly it's just the price you got to pay to get a below average priced home to live here.
