2451 Graydon Avenue This charming Unique Single Story Duplex features 3-bed main house PLUS a new construction 3bed/3.5bath / 1, 198 SF ADU is perfect for multi-generational living, or you can use part of the property as a full- time or mid-term rental! This unique property presents several possibilities for the new owner: 1) You and your extended family may comfortably spread out in both the main house and ADU 2) Since each ADU bedroom has a private ensuite, potentially you could take one & rent out two plus the main house – and Enjoy mortgage-free living! You could also just live in the ADU or main house and rent out the other 3) Rent out the entire property for a steady monthly income. Located on a quiet street with mountain views, close to parks, great schools, shopping & dining along the 210 Fwy and trendy Uptown Monrovia. Homes with NEW CONSTRUCTION ADUs do not come on the market very often – and even rarer is an ADU with 3 beds & 3.5 baths. Come see this unique property before someone else does! (Long-term estimated rent: front $3, 500 / back $3, 700; mid-term estimated rent: front $5, 800 / back $5, 500). You may even be able to purchase this home based on its rental income alone by using a DSCRloan — meaning the rental income could cover the mortgage payments. It’s a great opportunity for both investors and owner-occupants who want their property to pay for itself! Monrovia is also one of the few cities that still allow short term rental!
