See if any of the other units in your complex are being rented and for how much.Here's what you need to consider when doing an analysis on a SFR/condo/townhouse:Expected Rent, then subtract from that:Vacancy Loss, typically 5-8%Repairs and CapEx: 12-15% combinedManagement: 10-12%P&ITaxesInsuranceHOABased only on your numbers above, I calculate you'd lose about $14/month.

You should factor in an expense ratio of 35%-50% of the gross income then subtract the mortgage payment.

How I would approach, for simplicity, take your terminal value, subtract costs to renovate and lease-up (don't forget to include leasing commissions if you will have someone else do it), subtract your financing costs (interest, loan fees, etc), subtract a profit margin that you want to make for the headache of doing all of this, and then you will land on your offer price.Best of luck.

Calculate the Realized Gain on the Rental PropertyThen, we figure out the realized gain on the property by subtracting $130,000 from $430,000, and we get $300,000.4.

I typically subtract 3%, of the ARV.Realtor Fees: What is the commission you are willing to pay your listing agent (unless you are the listing agent) and the buyer's agent.
