All are perfectly functional now, but could pull higher rent with replacing the flooring, and updating the kitchen.My current financing setup for this deal would be $235,000 from the HELOC I already have secured.

IE rent to a tenant for >12 mo,  dating before marriage, no late payments then with a down paymetn (long story here)  I'll sell on either a contract for deed (typically mobile homes on land) or a note and mortgage (regular nicer houses). 

Could any of you guide me on what I should do initially to secure financing?

I will do my regular due diligence when dealing with a new partnership and any deals they find. 

Whether it's a private chat group, email support, or regular check-ins, make sure there’s a way to get ongoing help.7.

I plan to manage the properties myself until it conflicts with my regular job.I would appreciate any advice on these markets to ensure success and connect with local investors.

The building next to yours looks much nicer and has THREE security vehicles parked in front.

If I were in your and/or your mother-in-laws shoes, I would go to a local bank and use the free and clear house to secure a $150K+ line of credit. 

And if a property is owner occupied, how can you secure a loan with a hard money lender not being able to view the home to estimate repairs?

I make my regular interest-only payments for the first 7 or 8 months, and my interest-only period lasts 5 years.
