I've been an excellent student of calculating repair costs and ARV.

For FHA, I would ask your lender to confirm that they considered the 100 mile rule in calculating DTI.

Many voucher holders also work and so sometimes they will have a higher amount to spend than someone who doesn’t work because they can pay up to a % of their net income from the HA’s calculations, often 30-40%.

When we order an appraisal, we are handing in a rehab budget to the appraiser and they will use this to help calculate an ARV which is used in the lending calculation. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Also, keep in mind occupancy is usually calculated yearly.

Accurate records of all expenditures are essential to claim deductions and calculate the cost basis for future capital gains taxes, including depreciation recapture.This post does not create a CPA-Client relationship.

Use the BP Calculator to get a better idea on your costs.

Everyone says to find properties and build a buyer's list, but neither matter if you can't calculate the repair costs and also get access to a friend or colleague who has MLS so you can do a proper and real ARV (the other part where all wholesalers fail).
