Hey Rami Henen - you're on the right track.  

I'm currently looking for a platform to track business expenses for tax purposes.Thanks for the advice! 

Are you tracking your current response rate?

Do not cut any corners on estimates to make something look better on paper but is not real..Track all income and expenses by project and in report form and review them regularly with a few other people you trust and understand your goals and plans.   

@Andrew Martin...You are on the right track.  

who's going to track materials and labor costs for you? 

It has done me a lot of justice.

And Quicken/Rocket Mortgage has a really bad track record of NOT completing their loans.

Track Comparable SalesAlthough we are still hovering near the all-time lows with respect to the 10-year treasury, consider that for every 1 percent rise in interest rates it takes somewhere in the neighborhood of an 8 percent increase in Net Operating Income to remain at par as far as your property value is concerned.

The underwriter would not give us credit for the rental income because we didn't have 2 years of tax returns showing rental income.So basically they looked at the duplex as a mortgage expense on our debt to income ratio, but gave us no credit for the rental income.Once you get a track record of rental income, the underwriters will give you credit for a large portion of it.
