| $30k · 2% · 3yr (low-cost market) | $809.28 | $29,133.99 | $866.01 |

| $20k · 3% · 2yr (small first property) | $809.62 | $19,430.98 | $569.02 |
How This Calculator Works
Enter the all-in cash target (down payment + closing costs + operating reserves), the rate a savings account pays, and the years until you want to purchase. The calculator solves for the monthly contribution that reaches the target.
The Formula
Required Monthly Saving (Sinking Fund)
FV = goal amount, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
Saving $50,000 over 4 years at a 3% rate needs about $982 a month. Deposits cover roughly $47,122; interest adds about $2,878. That builds enough cash to acquire a $200,000 rental at 20% down with closing costs and 3 months of reserves — a realistic first rental in many US markets.
Key Insight
Most first-time investor landlords underestimate the cash needed at closing. Down payment is the obvious 20%; closing costs add 2% to 5%; and operating reserves (3 to 6 months of mortgage + taxes + insurance + maintenance) are the often-skipped piece that prevents emergency mid-vacancy stress. Build the savings target against all three; under-reserving is the #1 reason first-time landlords sell at a loss.

Frequently Asked Questions
How much do I need for a first rental?
Down payment (20% to 25% of price), closing costs (2% to 5%), and operating reserves (3 to 6 months of expenses). For a $200,000 rental: $40k to $50k down + $5k to $10k closing + $5k to $10k reserves = $50k to $70k total cash at minimum.
Can I use a primary-residence loan for a rental?
Only if you actually live in it — house hacking. Buying with 3.5% FHA or 5% conventional financing and then renting it without occupying is mortgage fraud. The legitimate path: live in it 12+ months, then convert to rental and refinance or simply hold the original loan.
Should I save or take it slower with house hacking?
Depends on personal preference. House hacking (buy with low-down primary loan, rent out other units or rooms) reduces the cash needed but locks you into living in the property. Pure investor purchase requires more cash but full property control.
What return should I assume?
For 2-to-5 year horizons, use high-yield savings (currently 4% to 5%). Longer horizons (5+ years) can support a conservative bond mix; aggressive stock allocation creates timing risk if the market dips in the year you want to buy.
What about loan reserves required by lenders?
Many investment-property lenders require 6 months of PITI reserves in addition to closing costs. Some require reserves equal to total monthly obligations across all properties. Build the larger requirement into your savings target.
When is this calculator unreliable?
Less reliable when investment loan rates 0.5-0.75% above primary (7-9% 2024), when 20-25% down required (vs 3-5% primary), when DSCR loans available for landlords (rent qualifies), when cash-out refi from primary substantial source, when closing costs 2-5% purchase price not included, when cap rate analysis (NOI / purchase price target 5-10%), or when 1031 exchange tax deferral substantial. 'House hack' (2-4 unit + FHA 3.5%) substantial first-investment strategy.
