Leverage will be based on whether the land is entitled and borrower track record but 50-60% is the norm, not 80%.

However, a larger home may consider another can or two in certain locations based on proximity to the kitchen or bathroom.

Where are you based out of? 

I'm a fan of gated yards and higher-end security doors and will install chain link and even some wood privacy fencing if I think the house/area warrants it.  

Quote from @Efrain Flores: Quote from @Tim Delaney: Based on rent of $1500-1600 and mortgage payment of $1700-1800 which doesn’t even include maintenance, management or capex it doesn’t seem to make any sense to keep it as a rental.

They already have a track record (good or bad) with you, so you can decide based on payment history, inspections, etc.

Based on my experience, you're right that many lenders allow the use of a second home mortgage for properties intended for personal use, provided you meet certain conditions.

I built this budget template based on my research but am only seeing bad investment returns / don't really know what I'm doing and would appreciate any feedback you all have to offer.

If one or more units are vacant, the remaining units often don’t provide enough cash flow to cover expenses, making it harder to meet operating costs.Maintenance costs: A fourplex comes with four times the appliances, plumbing, HVAC systems, and other components to maintain, leading to significantly higher repair and maintenance expenses than single-family homes.If you want to see the detailed calculation, read this BP blog - More Units Doesn’t Mean More Money—Why a Single-Family Home Can Beat a Fourplex.Resale value: Multi-family properties have a limited buyer pool—mainly investors—who base their offers on CAP rates.
