Santiago duplex: setting a cash-flow floor before counting appreciation

I’m comparing a five-bedroom Santiago duplex with higher-yield options in cheaper markets. The duplex has only a modest current yield, but Santiago appears stronger on employment, transport and eventual resale liquidity. The cheaper alternatives produce more cash now but may be harder to exit.

My concern is turning “future appreciation” into an excuse for weak numbers. Would you require a minimum cash return after vacancy, management, maintenance, insurance and property tax, then treat growth as upside? I’m looking for ways this Santiago deal fails, not reassurance.
 
I’d give appreciation zero weight in the base case. First require positive net cash flow after realistic operating costs and financing, then test whether it survives a rent reduction, vacancy and a repair. If it only works because Santiago might rise in value, it doesn’t currently work.
 
What does “modest current yield” include? Gross rent divided by price tells you almost nothing here. You need the actual rent roll, unit configuration, lease terms, expected tenant turnover and whether either unit is currently vacant before anyone can judge the downside.
 
I disagree slightly with setting one rigid cash-return floor. That can push you toward apparently high-yield properties with worse buildings, tenants or exits. I’d still exclude appreciation from the base case, but compare total risk across several scenarios rather than letting one percentage decide everything.
 
Model vacancy and turnover separately. Vacancy is lost rent; turnover can also mean cleaning, repairs, advertising and a gap before the next lease. With only two units, losing one tenant could remove a large share of the duplex’s income at once.
 
Emma’s question is the key missing piece. Build normalized annual income from supportable rents, subtract vacancy and every operating expense, and only then apply debt service. I would not call the result a return until those deductions are visible line by line.
 
Include management even if you expect to manage it yourself. Otherwise you are counting your labour as property profit, and the numbers become misleading if your circumstances change or you need someone local to handle the building.
 
The claimed liquidity advantage also needs testing rather than assuming. Who is the likely future buyer: an investor valuing the rent, or an owner-occupier valuing the layout? A five-bedroom duplex may appeal differently depending on how the rooms and two units are arranged.
 
Employment and transport arguments can change block by block in Santiago. Look at the actual route tenants would take, nearby competing rentals and who the current occupants are. City-level strength cannot rescue a property whose immediate location or configuration limits demand.
 
That also answers amitchell’s caveat. A lower cash yield can be rational when risks are genuinely lower, but “Santiago” alone does not establish that. The base case should stand without growth, while the location case explains why the downside or exit may be better.
 
I’d make three columns: expected year, difficult year and financing shock. Change vacancy, turnover costs, maintenance and borrowing cost rather than just cutting rent. If the difficult year requires cash you cannot comfortably contribute, the appreciation discussion is secondary.
 
Be careful comparing cash returns if the properties use different leverage. A financed Santiago duplex and a cheaper all-cash property can look very different simply because of debt. Compare unlevered property performance first, then separately examine what financing does to your own return and risk.
 
Yes, and financing sensitivity should include renewal or refinancing rather than only the initial payment. No need to predict a particular rate: calculate the highest debt cost at which cash flow remains acceptable. That gives you a clear boundary instead of a hopeful forecast.
 
For property tax and insurance, use figures tied to this exact property wherever possible, not broad Santiago estimates. Also confirm what is insured and whether the duplex’s recorded use and physical arrangement match the income plan. Those details can alter both recurring costs and the eventual buyer pool.
 
Maintenance reserves should reflect the building, not a convenient percentage copied from another deal. Roof, plumbing, shared areas and deferred work can overwhelm a modest yield. A pre-purchase inspection and a list of likely near-term projects would make the stress case much more meaningful.
 
How do you intend to lease the five bedrooms—two complete units, individual rooms, or some other arrangement? A room-by-room income assumption may bring more turnover and management than two standard tenancies. The operating model needs to match the rent figure being used.
 
After all that, the minimum return should be personal but explicit: enough to compensate you versus your realistic alternatives, with appreciation set to zero. If ordinary vacancy and reserves already make cash flow negative, I would reject it. If only the stress case is negative, decide whether that cash demand is tolerable.
 
The cleanest decision rule here is: verify sustainable rent, deduct full operating costs, stress financing and one-unit vacancy, then assess the cash needed during recovery. Only after it passes should employment, transport and resale liquidity break a tie. That prevents appreciation from repairing a weak spreadsheet while still allowing quality differences to matter.
