Analyzing a deal/ Newbie

[Abad Marroquin]

6 Mobile homes in 3 acres of land for 119K in a decent area.

All built around 1995.

$All are occupied and each generating 105/week.

Potential montly groos income $2520/month.

with a 5% interest rate loan the payment would be around $600/month

Using the 50% rule, I should be getting a $825/month.

Does this sound like a good deal?

After 20 years, are mobile home still worth investing?

Using Brandon's spreadsheet, do I treat them like regular houses?

I guess what I want to know if mobile homes tend to depreciate faster or if they have a shorter lifespan than a regular home.

Thank you for your help!
