I'm not physically in Texas, but I'm happy to answer any questions you have.

I'm looking to build a 2500 sq ft two level ecofriendly single-family home which incorporates natural surrounding into the design, I'm trying to figure out what my cost should be for architectural plans: elevation, floor plan, mechanical, plumbing, electrical, etc.  

You have security deposit and it's something you can now incorporate into new leases.

I even have a fee in my lease if they want me to physically pick up a rent payment.

If not, we’ll need to have one ordered for you.Entity Documents (NEEDED FOR PREAPPROVAL):LLC/LLP i.Copy of Articles of Formation/Incorporation ii.Copy of fully executed Operating Agreement/Partnership Agreement (all pages & amendments) iii.Certificate of Foreign Qualification (if applicable) Corporation i.Copy of Articles of Formation/Incorporation ii.Copy of fully executed Corporate Resolution designating authorized signer(s) for the Corporation iii.Copy of fully executed Corporate Bylaws iv.Copy of stock certification v.Certificate of Foreign Qualification (if applicable)Identification (NEEDED FOR PREAPPROVAL): Copy Driver’s License or Passport for each Guarantor.Rent Roll (NEEDED FOR PREAPPROVAL): We’ll need to get an understanding of the current cash flow of the property.

Following here, @Chantel were you able to find an updated MN lease that incorporates the 2024 changes?

If you’re going conventional on a second home, you might want to consider putting even more down and make sure that your debt to income ratio is <41%, and credit at or above 780, ideally, as the GSE’s just made changes to the Loan Level Pricing Adjustment (LLPA) just got even more expensive effective 05.01.2023 but most lenders will either incorporate this into their pricing or will then. 

Make sure you use a state-specific lease so that you are incorporating any specific regulations and disclosures relevant to the state you're doing business in.

Digitize physical receipts for easystorage.

As my wife and I are both over 45, we require a distinct approach to ensure we can retire within the next 10-15 years without having to work, particularly in physically demanding jobs, until our final days.
