This felt like they were turning me into their money-making machine.If they’re charging $10K upfront, plus $200 per month, and taking 50% of the profits, why aren’t they putting in 50% of the work or covering 50% of the down payment?

It will give you a lower interest rate on both properties because you bought them as owner occupants, and it will require less down payment to get into. 

In this type of situation, they want low interest rate with low down payment also.

For example, if you need $7,000/month to replace your current income, and each property costs $250,000 and generates $300/month in cash flow, the amount of cash you'll need just for 25% down payments is $7,000/$300 × $250,000 × 25% ≈ $1,458,333.

QB really is not made well for landlords and landlords leave QB every day for better software, payment processing is really expensive, and with QB there's no tenant portal for your tenants to schedule payments or push maintenance requests. 

For example, the buyer, if they find problems with the property or stop making payments, can blow up the seller's credit.

@Marcos Carbi  If you want to allow a payment plan, Tell them this is the best I can do:Pay $xxx cash by tonight at 8pm for November's rent. and then beginning Monday Jan 20, pay $450 each Monday (in cash?

Breaking Even & Potential Cash Flow•Your goal of breaking even in Year 1 is very achievable, especially with a 5% down payment and PMI removal via renovations.

Given the market conditions and your hard money loan, it might be wise to first calculate your monthly holding costs, including loan payments, taxes, and maintenance.

If you sell, you could access the equity you’ve built and put it toward other investments or save for a future down payment.
