SpillDeals — Best For: Florida Deal Discovery
Who it's for: Florida investors who want to see every live listing graded A-F without doing math.
SpillDeals is the only tool built specifically for Florida. It scrapes live MLS data across 20 FL markets daily, then automatically calculates cash flow, cap rate, and ROI for each listing — and assigns an A-F grade so you know instantly if it's worth investigating.
Unique advantages:
- Only tool with automated A-F grading across all loan types
- Section 8 voucher rate data baked in — rare
- 17 loan scenarios (FHA, DSCR, VA, conventional) on every deal
- $29/mo Pro vs $74-99/mo for Mashvisor
- Free tier includes real deals (not just a calculator)
Limitations: Florida-only (by design). No national market if you invest outside FL.
Mashvisor — Best For: Airbnb/STR Analysis
Who it's for: Investors analyzing short-term rental potential (Airbnb, VRBO) across multiple US markets.
Mashvisor's strength is its Airbnb occupancy rate data — it aggregates actual STR performance data and projects your revenue if you run a short-term rental. For investors evaluating Miami Beach condos, Orlando vacation homes, or Naples luxury rentals as Airbnbs, Mashvisor is the best specialized tool.
Limitations: No deal-level grading. $74-99/mo is expensive. Lacks Section 8 data. No FL-specific loan analysis.
DealCheck — Best For: Custom Underwriting
Who it's for: Analytical investors who want to build detailed custom proformas and save specific deals.
DealCheck is a spreadsheet-replacement. You manually input a deal's details, and it calculates 40+ metrics. Great for serious underwriters who want to model different scenarios (what if rents drop 10%? What if I refi in year 3?). Not great for discovery — you have to bring your own deals.
Limitations: No live deal feed. Manual data entry. No automatic grading. Better as a secondary tool after you've found deals on SpillDeals.
BiggerPockets — Best For: Education & Community
Who it's for: New investors learning the fundamentals, or experienced investors who want community and networking.
BiggerPockets is the largest real estate investing community in the US — 3M+ members, active forums, excellent podcasts, and a solid deal calculator (free). It's where you go to ask questions, find local investors, and build your knowledge base.
Limitations: Deal calculator requires manual input. Pro ($39/mo) unlocks the calculator but it's still not automated. Not a deal-finding tool in the same sense as SpillDeals.

Frequently Asked Questions
Is SpillDeals free to use?
Yes. The free tier shows real graded deals (C, D, and F grades). Pro ($29/mo) unlocks A and B grade deals, full financial breakdowns, and deal alerts. No credit card required to start.
How is SpillDeals different from Mashvisor?
SpillDeals focuses exclusively on Florida and automatically grades every live deal A-F. Mashvisor covers the full US with deeper Airbnb/STR data but no automated grading and costs 3× more. For FL buy-and-hold or BRRRR investing, SpillDeals is purpose-built.
Can I use SpillDeals and DealCheck together?
Yes — that's actually a great combination. Use SpillDeals to find and screen deals fast (A/B grade filter), then pull the best deals into DealCheck for deeper custom proforma modeling before you make an offer.
What does SpillDeals' A-F grading system mean?
SpillDeals grades every FL property based on cash flow, cap rate, and ROI relative to the market. A = top 10% of deals (strong positive cash flow, 6%+ cap rate). B = solid investment. C-D = marginal. F = negative cash flow. Grades are calculated across 17 different loan scenarios so you see the best financing path.
