[VALIDATION NEEDED] My landlord just accidentally validated my startup idea

So I'm sitting in my cramped apartment last week, debugging code at 2 AM (classic indie hacker life), when my landlord texts me:

"Hey, can you remind me when your rent is due? I have 47 tenants and keep losing track of everyone's dates."

My brain immediately went: Wait, what?

This guy owns multiple buildings, collects $200K+ monthly, and he's tracking rent in... checks notes... a literal notebook and sticky notes on his fridge.

The rabbit hole deepens:

• Called 3 property manager friends

• ALL using spreadsheets or pen & paper

• Missing payments cost them 15-20 hours monthly in follow-ups

• One lost $8K last year due to "tracking errors"

Current solutions:

• Big property management software: $200/month (overkill for small landlords)

• Generic CRM: Doesn't understand rent cycles

• Spreadsheets: Error-prone nightmare

My lightbulb moment:

Simple rent tracking SaaS for small landlords (1-20 properties). Automated reminders, payment tracking, tenant communication. No bloated features. Just works.

Built an MVP over the weekend. My landlord tested it and said: "I'd pay $30/month for this right now."

But here's my doubt:
Is this too niche? Are there enough small landlords struggling with this, or did I just find the one guy who's organizationally challenged?

Quick validation questions:

• Know any landlords who seem disorganized with rent collection?
• Would simple = better than feature-heavy for this market?
• Red flag: Is this problem "annoying" or "desperate need" level?

Honest feedback needed, am I onto something or chasing a ghost? 👻

Building in public if this resonates. First 100 landlords get lifetime access for $99.
