Cash Out Refi Question

[Taye N.]

I purchased a Duplex for $574,000, It currently Rental income was A=unit 1100, B=1150 total: $2250

I remodel both units and rerented with a 2 year lease. A=$2100 and B=2100 total $4200.00

So basically I almost doubled the rental income.

I had put down 25% percent because it was not home owner occupied, Down payment = $143,500

Repairs and remodel cost for both units about $30,000 totaling around $180,000 on my HELOC.

I would like to do a cash out refi, to pay off my HELOC, however since it a duplex, I dont know ARV.

1.How much would my house need to appraise for me  pull most of my money back out? my bank only does 70 percent non-owner occupied. Does any know of any banks or loan companies that does 80 or even more with good interest rates?

2. Since I doubled the income does it increase the value of the property? The place is cash flowing, about 350.00 a month.

3. Does duplex use the income approach? or is it still comparable?

thanks!
