buy and hold rental with a private loan calculator?

[James Register]

hello,

I know how to figure cost, fix and upkeep on a rental property. My problem is finding a calculator/spreadsheet or pro forma workout program. I was hoping someone could help me. All the standard calcultors take the 20 year mortgage as part of the projections.

For example: I brought a $100,000 sfh for $80,000 put $8000 dwn and borrowed $72,000 from a private lender @ 7% for 2 years. I would then lease option the sfh to a tenant for 2 years.

Is there a spreadsheet or a calculator out there? Thanks
