I think you will want to prepare a line item budget showing exactly what was done and the costs involved. 

Looking at this chart from my excel sheet it looks to be a bad investment, Even bringing the purchase price down by over 100K still brings me negative cashflow over the first 2 years due to the rehab budget.  

What is my budget?

I am just starting out and I am looking for something budget friendly.

With these payments and truck and trailer payment my DTI ratio is still hi since showing not much income on taxes.

PP-42,000Rehab budget - 10,000Projected ARV we had was about 80kPotential rents - 1,000/moWe got our pre-appraisal back yesterday for based on the rehab plan came back at 108,000. 

I think that is in part due to the credit report and budget analysis that we do on each tenant application that we receive.

I also budgeted 6000k/yr for marketing.

Many in my area are really beat up, how do I go about finding out the estimated costs for budgeting purposes to see if it's a deal or what I can offer for it?

My capex budget includes roof 25 year life span, floors 10 year life span,appliance and hot water heater 12 year life span, hvac 20 year life span, bath and kitchen remodel 20 year life span.
