Too Cheap? Loan expense question.

[Jeff S.]

Planning on moving into a rental and doing some rehab. I have a credit line and other avenues to cash so financing is not totally necessary.

I am contemplating living there 2 years, selling and saving on a 250k gain. If I refinance and sell in 2 years I lose the closing costs invested.

It is possible I'll add a unit and simply will feel unable to part with it because can't find anything comparable, and in that case financing could be higher, and market might not be great to sell then either. If either of these things happen then not having tied up financing would be regretable. Credit lines might also increase.

What would you do?
