Backstory: My friend owns a bunch of rental properties and is constantly dealing directly with tenant when there are issues.
The Idea: A tenant management app for landlords.
Deep Dive: You would build a mobile app for tenants to sign into to submit maintenance requests. As you scale, you could build a bunch of additional features to use with the renter:
You could also build out features for the landlord to help manage properties:
Validation: LandLordy already exists in this space but they lack some features around maintenance and coordinating with handymen/contractors to fix issues.
Monetization: You could offer a free version that tracks one property and has limited features. Additional versions would unlock more features and have a per property fee. This scales as your customer scales.
Steps to Launch: To MVP this, you would have to build a decent set of features. You could reach out to any landlords you know to get their feedback and get them to prepay for a year at a steep discount. This would give you market validation in addition to a some cash runway to build your first version.
