IME (in my experience), you would charge a fee (say 50-100 basis points) to the banks/investors, often times based on the either the commitments or the outstanding balance of the fund. 

I'd be delighted to show you some examples of our investor clients achieving these outcomes with recent purchases. 

As noted, commission are always negotiable as are brokerage options (full service to discount companies that pretty much just post it on the MLS and you work with all calls, offers, etc) and an agent can go over likely net out scenarios with you and give you an idea what you likely will be able to net after closing expenses and paying off the mortgage balance. 

@Sebastian AlborsIn my experience, buying a single-family home (SFH) in Asheville and house hacking with a family member like your brother can be a smart way to balance costs.

There are significant details that I'm choosing to leave out regarding rent payments and balance left for the owner as you terminated the lease early. 

This month we have placed three opportunities with investors looking to balance their portfolio.

I prefer a balance between cash flow and capital appreciation.  

Here are the details of the property:Property Overview:Location: Texas2 lots, 2 warehouse buildingsFinancials:Mortgage: $4,897/month (balance: $530,000)Insurance: $830/monthProperty Tax: $1,800/monthBuilding 1:1 tenantRent: $7,570/month12,000 square feetBuilding 2:3 tenantsTenant 1: $2,850/month (5,000 square feet)Tenant 2: $1,793/month (2,500 square feet)Tenant 3: $895/month (1,250 square feet)The property was appraised for $2,200,000 three years ago.Given the current rental income and expenses, the cash flow is decent, but my family friend is looking to explore options that could potentially yield better returns.Would it make sense to:Sell the property outright and invest in higher cash-flow opportunities?

In any case, I doubt many people on BP would want to buy properties in Switzerland given the very low returns that can be achieved there.

The idea is to find a pocket or neighborhood that offers the right combination of estimated ROI and rental demand, giving a balance of cash flow and tenant demand.In my view, this approach provides a more reliable signal of demand than relying solely on pricing adjustments or short-term market trends.
