That's assuming 10% management, 5% vacancy, 5% repairs, 5% capex, mortgage, tax and $1700 per year insurance and assuming you put 20% down so no PMI

I want to be as accurate as possible on my repair prices.

I don't want to hire a collection company who sends out one or two mail to the company or just make one or two phone call and close the case.

Since the property is located so close to you, and you already know that it is vacant along with recent history, I would try to locate the home owner's phone number and call him or her directly.

Paul,...If you're going to wholesale like a professional, only pursue deals that are worth Cash Buyers' time (target for 60% ARV if you're not confident about estimating repairs)Some wholesalers aim to lock up as many houses as possible and then walk away when their 2 cash buyers won't buy [bad] deals.

Have been using our trusted subcontractors for all repairs.  

If you use the proceeds let’s say 10k, from that 30k, for an repair  is you will have 10k of rental expenses.

yes that is correct and I incorporate all the expenses and for capex, I esitmated 10% for repairs being safe with a margin percentage.

The best way to do that is to get on the phone with a whole bunch of them.

There have been three break-ins since June and repairing the damages have been draining my budget.
