As a result I must Study the market and know what i’m worth. 

For instance:If your area has many corporate offices or conference centers, you're likely to attract business travelers.Family-friendly suburbs with parks and schools often attract families.Downtown locations near nightlife are popular for groups and parties.Review Competitor ListingsSearch for successful Airbnb listings in your area and study their target audience based on:The language in their descriptions.Their reviews (guests often reveal the purpose of their stay).The amenities they offer (e.g., desks and Wi-Fi for professionals, cribs and baby gates for families).Evaluate Your Own SpaceYour property’s layout, amenities, and location may naturally cater to a specific audience.A cozy 1-bedroom apartment downtown might be ideal for professionals or couples.A 3-bedroom house with a yard might appeal more to families.Proximity to nightlife might cater to party groups.Experiment and AdjustIf you're unsure, start broad and monitor who books your property.

During my REI investing journey I've done 7 1031’s, then followed each of these up with cost segregation studies.

Studies have shown that guests don't want to book for a full week anymore, they'll pay more per night for a shorter vacation of 3 or 4 nights.

Im new to the investing world and am still in the early stages, I've been studying and researching for the past five years.

Study the market.

Do a case study.
