I recommend having your deals secured by a mortgage and a promissory note for your investors.

Are you priced fairly and have a low security deposit?

While I secured the initial financing for the property, I have two other partners/groupings (a total of 6 people) that are contributing to the closing. 

If your DSCR has improved or market rates have dropped, refinancing might secure you better terms and improve cash flow.

You want to make sure that asset is secure.

But if do a BRRRR from far away that's risky too, without a really good and trustworthy team in place and lots of checks and balances (security cameras, someone local to check on your property) and the ARV and refinance aspect can be challenging.  

Many of our clients have done this and secured much better terms....EricThis spreadsheet decision is based on what you can afford and when you expect interest rates to fall.

We know we want to create an llc but is it difficult to secure a loan?

You can secure a 30 year fixed on a 1-4 unit residential and a commercial building.

I always research companies first before doing business, but that comes from my training and working on security issues, especially after having my sites hacked.
