I am 1600 miles away from three residential properties I just purchased in Jackson, Mississippi. 

With a purchase price of $250k, your rent is WAY too low!

Retain proof of that notice and make sure you include the new tenants right forms required by the city now.

I've got about $525K in equity in the property, but lenders have told me that I cannot get a HELOC to access that equity for additional purchases because the duplex was financed as an investment - they have said TX law dictates that HELOC can only be used on primary residences.

I am a rookie investor hoping to purchase my first property within the next 90 days.Kwanza Hi Kwanza,The first thing you'll need to decide is whether or not you want checkbook control of your self directed IRA. 

An alternative could be including photos of plants in your design.

But i was able to achieve the elusive infinite return on a majority of my RE and all of my investment RE that I purchased prior to 2020.Infinite return has the benefit that the finances are not the hindrance to scale.  

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.

Include a sweet outdoor area maybe with a pergola, jacuzzi feature.

My partner and I keep an excel spreadsheet of rent, our purchases, utilities, taxes, insurance, and money spent on contractors.
