This is the percentage of costs (purchase and rehab) covered by the loan.

It's certainly worth the cost of having him review the contracts and inform you of your rights.

Your estimate seems low, but even at that cost, it will not add that value.  

If the tenant is claiming to be living in a hotel, she may try to get you to reimburse for that cost unless section 8 has a new process to reimburse them for this... which sounds absurd but I'll let you deduce whether or not you're dealing with someone who is used to paying for things out of their own pocket. 

At least that avoids the banks closing costs right now.

I would strongly consider building equity to make a stronger down payment and further decrease your monthly cost. 

How about opportunity cost?

This creates two loan payments ($100,000 of equity and $300,000 on the new mortgage).Key NumbersHome Equity Loan Interest Rate: 6%Mortgage Interest Rate: 7%Rental Income: $3,000 per monthExpenses (management, taxes, insurance, maintenance): $800 per monthIncome and ExpensesMonthly Rental Income: $3,000Monthly Expenses: $800Monthly Mortgage Payment: $2,000ExplanationThe investor earns $3,000 in rent each month.They pay $2,000 on the investment property mortgage and $800 on other expenses.This leaves $200 profit each month or $2,400 per year.However, you have to pay $6,000 interest on the equity borrowed.This leaves you with an annual loss of $3,600.While the rental property generates positive monthly income, the interest cost of borrowing the initial $100,000 results in an overall loss.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

Would be curios if folks have also just included the cost of utilities at this price and left it unpermitted.
