It's impossible to answer your question without knowing how much you have to spend to acquire the house.

I would acquire in cash and then refi into longer funding. #4.

Do you acquire properties on top of being a realtor? 

Last week I acquired my FIRST wholesale deal!

It's a business - acquiring/building, managing, and growing a business.

I recently acquired my first primary residence and am seeing ways I can best utilize the space for real estate investing.

When we create our business plan, we also include our exit plan.We'll only proceed if we can clean this up, acquire new tenants at higher rents so we can increase our NOI, which in turn should reflect our cap rate and profits.Since this asset class is new to us we will tread cautiously.Scheduled to preview tomorrow. 

I have amassed a decent network of vendors, so definitely looking at fixer uppers.Eventually, I hope to grow my portfolio to acquire commercial loans for multifamily deals, I haven't started purchasing investment properties, only have my private residence.
