I'm currently planning to purchase a commercial multifamily building in Chicago with the proceeds of a 1031 exchange.

Most of the time I do the BRRRR strategy and I have scaled to 9 doors now, one of which I'm planning to flip.

Just keep in mind that using that emergency fund to buy your next property and having tapped a HELOC already may leave you in a bad spot if you run into a similar problem again.Also, I’m not 100% sure, but I have heard that personal loans don’t your credit more so than other types of debt so be sure you look into that if you go the personal loans route and then planned to finance your next purchase soon after.

The replacement property and planned improvements must be identified within 45 days and completed within the 180-day exchange period.

A good tax 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 business taxation, financial planning and tax planning.I would also recommend looking for a accountant willing to work with you throughout the year.

If you are accredited, the best thing to do would be to invest 50k into a syndication and soak up all the knowledge of how it works from an experienced operator before you make the decision whether it's your plan.

I plan to live in it and then rent it out in a year. 

I’m trying to keep things moving, but this $20K requirement is throwing a wrench in my plans.

If I have several options, I would prefer a HELOC with no initial draw requirements (i.e. to establish a literal line of credit that I have no specific short term plans to use), i.e. not something like the better.com HELOC. 

They can offer valuable insights into the local market, potential rental yields, and specific considerations for a rehab project like the one you're planning.
