Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I would talk to a few lenders and see what they say. 

Connect with experienced real estate agents using BiggerPockets Network, local brokerages, and online reviews.

No need to be obsessedFor me the reason I do it is 5 years down the line I will start working part time on my w2 and get more into real estate like maybe as a private lender and also doa  few flips and a  few joint venture dealsIntention is to not have the 9 to 5 ratrace etc and also work  from anywhere

Any help or recommendations for an investor-friendly lender would be great. 

Your mortgage lender may require you to occupy within a shorter time frame, which may be legal justification for giving a shorter notice.

Even with private/seller financing, if you're househacking, the lender will still be subject to the ATR rule and ignoring this will cause problems for everyone.

Make sure to connect with local lenders and brokers as well, it will be beneficial for achieving your real estate goals.

Occasionally, if the deal isn't as good lenders will require you to fund the rehab out of pocket.The problem you'll likely face is getting renters in the storefronts.

SBA lenders are confident the deal is lendable, but SBA rates at prime plus 2.5% are high, and I don't want to risk default.
