To me I count those things as probably more important than the actual deal itselfSo here are the numbers:Purchase price: 70KRenovation costs: 26K (I originally estimated 15K hahaha I wish)Closing costs: 2KAll in cost of 98K.Currently rented: 1200 per month.The bank appraisal with my local bank just came back at 134K and with a LTV of 75% I am eligible to refinance out 101K on the total deal.I am only refinancing 90K which will leave my all in costs at approx 8K on the deal.After PITI and reserves for maintenance, capex, vacancy, and management I will cash flow approx 200 a month with a 23% CoC return!

I'm a Broker of 20 years and the reality is that you become a target, you are considered an expert in your field (even if you haven't sold a thing, per the law in AZ) and you are held to a higher standard. 

Then, estimate $10 per sq ft for cosmetic damage, $15 per sq ft for moderate rehab, and $20 for significant rehab.

My policy is no more than two persons per bedroom (not counting children under two years old).

I would connect with some wholesalers in the area.Also, there are some alternative ways to invest in Real estate for a big return.. for example, there is a desperate need for corporate rentals (furnished short-medium term leases) that pay 3 times per month what a traditional lease would demand.

For interior paint I'll use a price per sq. ft. multiplier.

He will likely only have to pay a few hundred per month in this scenario though. 

My two cents.

The property cash flows and the rents per square food are about 20 cents too low.

If you want me to walk you through the process of examining titles and the checklist I've built up over time we can skype/discord.I'll review Idaho's tax-deed laws this weekend - in the mean time post your questions on Avvo as well (you'll have to do one question per post however but you can't beat free lawyer advice).Weird your state issues QCDs... and not a Tax-deed.You will have to learn to title examine on your own... do not go with title companies per property unless you have a massive bankroll (granted if you see a property that you know you'll win, you also physically visited it, go ahead and order a title search).You may be looking in the wrong states (there exists 1 state out of the entire USA that issues title insurance for tax-deed sales and also has extremely pro landlord laws).
