Blanket portfolio loans for San Marcos doors across county lines.
Built for investors who own multiple properties. Roll five or more rentals into one blanket loan with a single payment, free up capital to keep scaling, and release individual properties as you sell. A San Marcos-area portfolio often crosses three appraisal districts, Hays, Caldwell, and Guadalupe, plus more than two dozen MUDs and WCIDs, so we verify each parcel's tax stack before we size the loan. Business-purpose only, and every structure is set in underwriting.

How it works
Instead of a separate mortgage on every door, we structure one blanket loan secured by the portfolio, with the option to release individual properties as you sell them. It is built for investors scaling past a handful of rentals.
My San Marcos-area portfolio has doors in Hays, Caldwell, and Guadalupe counties. Does a blanket loan work across all three?
Yes, but every parcel gets checked against its own appraisal district. San Marcos, Kyle, Buda, Wimberley, and Dripping Springs sit in Hays County and Hays CAD. Martindale and Maxwell sit in Caldwell County, under Caldwell CAD, a separate rate sheet and a separate county clerk. A sliver of San Marcos and the Staples area sit in Guadalupe County. We size the blanket loan off each door's own county tax stack and clerk of record, not a corridor average, so a portfolio that mixes Hays and Caldwell doors underwrites accurately from the start.
Does the Austin Community College tax line apply to my whole San Marcos-area portfolio?
Only to the doors on Hays CISD parcels, which means Kyle and Buda, not San Marcos itself. San Marcos sits inside San Marcos CISD, which is outside the ACC taxing district, so a San Marcos door's stack runs 2.0666 per $100 with no ACC line. A Kyle or Buda door on a Hays CISD parcel carries an extra 0.1034 per $100 for ACC, landing at 2.2536 in Kyle. Mixing San Marcos and Kyle doors in one portfolio means two different tax lines on paper, even though both sit in Hays County.
How much do MUDs and WCIDs move the numbers across a multi-door San Marcos-area portfolio?
Enough to change which door carries the loan. Hays County alone lists roughly thirty MUDs, WCIDs, and district overlays running from about 0.01 to 1.00 per $100 on top of the base county, city, and school stack. A Sunfield or Crosswinds lot in Kyle adds close to 0.90 on top of an already-heavy 2.2536 stack, landing near 3.15 per $100, roughly 40% above Kyle's headline rate and about $9,450 a year on a $300,000 basis against $6,761 without the MUD. On a five-or-more-door portfolio, one MUD lot can move blended debt service coverage on its own, so we pull the special-district line on every property before we finalize terms.
Do I need to register every rental in my portfolio with the city, or just the ones in San Marcos?
Every long-term rental inside San Marcos city limits, one filing per single-family door and one per multifamily complex. The requirement has applied since January 1, 2021 under City Code section 34-821, and it applies to the San Marcos doors in your portfolio specifically. We found no comparable requirement in Kyle, Buda or on the Caldwell County side, but check each city rather than assuming those doors are exempt. Registration fee, renewal cycle, and inspection requirements were not published as of this writing, so confirm the current filing details with the city before you close.
A public improvement district (PID) assessment showed up on one door's tax statement. Does that affect the whole portfolio loan?
No, it's underwritten door by door, but it has to be found first. San Marcos has at least four active PIDs, Trace, River Bridge Ranch, Whisper, and Whisper South, and their annual assessments bill on the same Hays County tax statement as the ad valorem taxes but never appear on the appraisal district's own rate sheet. The dollar amount lives with the district administrator, P3Works, not the county. We pull the title commitment or the P3Works lookup on every San Marcos door in a portfolio before we size that property's contribution to the loan.
Can I release one San Marcos-area door from the portfolio if I sell it, without unwinding the rest?
Yes, individual property release is built into the structure. You sell the one parcel, release it, and the rest of the portfolio stays in place on the same loan. That matters in a corridor where the tax stack varies door by door: if a Kyle lot carrying a Sunfield or Crosswinds MUD line stops earning its keep, you can let that one go without repricing a San Marcos or Wimberley door elsewhere in the same portfolio. Subject to underwriting.
