Quote from @Dan Grove: Some combination of cash to seller, closing costs, repairs, construction, paying off arrears, assignment fees, commissions.   

Prices are around $300K for what he's looking for (total costs around $2000/mo, and income will be around $4439/mo... but if he has 2 roommates each paying $700/month, it's totally doable. 

I'd offer to pay more in commission than what you think is the "going rate" (not your exact words but what you are wondering) on my first deal or two with agents so that they are enticed to work with you.2.

Is it possible to sell or refinance one unit to pay the other off completely. 

I just got done making a YT video on the subject, so it's fresh on my mind.

My focus is on identifying value-add opportunities and managing properties to maximize cash flow and ROI.I’m here to connect with like-minded investors, share insights, and learn from others in this amazing community.

Do you currently have enough funds to pay first month’s rent and a security deposit?

If they fail to pay, then you can choose to try eviction or just hold the charges until the end of their lease and collect it from their deposit.

And if your investor friend’s private loan helps fill in any gaps, it might be worth considering that short-term pain for long-term stability.What do you think you’d focus on first... paying off that line of credit as fast as possible or jumpstarting the renovation to boost cash flow right away? 

In that case you need to pay the difference.
