How should I finance?

[Mickey Chambliss]

I have yet to purchase my first investment property but am in desperate need of advice on how to finance. After moving some things around, we will have roughly $65K in cash. I'm primarily interested in buy and hold using the BRRR method, but am flexible to any opportunity that may come up. These are the scenarios that I have thought about. Any one over the other you'd recommend? Or perhaps a suggestion that I haven't listed?

1. Pay all towards principle on my primary home, use HELOC for investment financing

2. Pay all towards investment property

3. Pay 20% down on a mortgage

4. Pay 3.5% down on a multi family, house hack and rent other unit

5. Hard money lender

My apologies, as I'm new to this I'm just not confident on how I should allocate my cash. Should I try and hold onto it for rehab costs and incidentals? Should I pay towards the property's loan, once some rehabs have taken place refinance? I know there are many variables that aren't listed but my primary question is what I should do with the liquid funds.  Any and all help is appreciated.

Thanks,

Mickey
