Purchase price: $900,000 Cash invested: $600,000 Purchased an existing short term rental fully furnished using equity from existing home here in Los Angeles.

Would doing a cash out refinance first to purchase next property hurt the process in anyway?

-- then maybe you get away with putting less in up front.

If they are not able or willing to honor their commitment to pay the full rent amount, it's time to start negotiating a mutual termination agreement, cash for keys, or eviction.

With that you are CHOOSING to pay the lender some money up front in exchange for a LOWER interest rate.

How much is the property, and what cash flow are you seeing?

At $490, it would cashflow around $195/mo and have a Cash on Cash ROI of around 9.9%. 

Some home builders are eating profits buying down the rates with the lenders to get into the 4's or 5's fixed but it comes at a steep cost many tens of thousands in fees upfront to the lender.

In the last 12 months, my company (LLC, sole owner) did over 1.2m in revenue, and i have cash to put a good % LTV down.  

Around here a lot of landlords offer section 8 tenants $300 cash when they move in with $0 security deposit.
