Could seller finance (not recommended) to reduce initial burden and spread it out over time

If I have some cash do you recommend clearing the loan or invest instead for next property with proper planning ? 

Any suggestions or recommendation would be greatly appreciated.

A lot of great advice in this thread - while Greg is right, it's a common mistake, and the right lender won't have you running into this issue - I always recommend buying in an LLC. 

In general, would you recommend getting a lawyer in the area where the LLC is registered?

My recommendation:  Punt. 

Bigger Pockets is a great place to find a real estate tax accountant.A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.You may want to consider working with your accountant remotely to expand your options.I would also recommend looking for a accountant willing to work with you throughout the year.

Based on the info in your post, my recommendation would be to turn these assets into well oiled machines and max out their NOI.

I would recommend that you get out to local meetup events, as that is where you will make the really deep connections to help you get rolling. 

Would love to connect to hear more about your experiences as well and any PM recommendations.
