Thank you both for responding. Currently I have purchased all these houses in the last year so I don't have a lot of equity in them at this point. The one property we rehabbed we are currently refinancing and paying off the private money we used for that. We will only get about 10k on top of paying everyone back off of that house.
Owner financing wouldn't work on this property because he is using this money to buy his own house after he sells. I could possibly work out a seller finance deal with him to start work on the one property and buy them out right in a year or so when we would qualify for a conventional loan more easily. This could get complicated though and would have a few more moving parts.
With hard money I am worried about the massive interest payments on about 300k for a year or so. I also need to make sure that again I'd be able to refi and get a loan to pay back the hard money. That is the part that worries me as I have heard the stories of people being unable to secure a loan on the back end to pay back the hard money. I have bought 3 properties in this same block and they have done fantastic in terms of rent and value so I know the deal is good and the numbers work out very well. I am just very nervous being over exposed to high interest payments and the loan refi on the back end.
