Refinance a mortgage

[Matthew Fassett]

Hey guys. My partner and I are looking at a duplex with a separate 1 bedroom 1 bath house for sale also so 3 units. Rent is 550 a month so 1650 a month total for the 3. Total expenses will be 1171 leaving us with a monthly cash flow of 459. Anywhooo. We have never done a refinance before on a mortgage or had a duplex with a house with it appraised. We will buy te property for 100,000 out 20,000 down and if it appraises for 130,000 after revo we will be looking at roughly 24,000 we can pull out for the refi for another deal. My question is. Is this a good route to go if we want to refi and get on to another deal or would it be better to buy 3 different single family houses? Thanks in advance
