What We Look For In New Castle County

We look at buildings with 5 or more units in New Castle County, from small walk-ups to larger garden-style communities, in stabilized or value-add condition. We compare in-place rents with nearby buildings, inspect roofs, plumbing and HVAC, and ask whether better management or targeted renovation can close the gap with the market.

Property taxes are a big line item for any Delaware apartment building. We estimate the tax bill as it will be after the purchase, because a sale can trigger a reassessment in many places. Delaware has no statewide rent control law, though local rules on notices, fees and deposits still apply. We get an insurance quote before we make an offer, because premiums have risen in most states.

We use modest rent growth assumptions, realistic repair budgets and financing that can carry the property through a slower year.

Evaluating Apartment Syndications In New Castle County

The data on this page turns into a short checklist for evaluating an apartment syndication in New Castle County.

• What vacancy does the plan assume? Rental vacancy in New Castle County is 5%. A plan that assumes much lower vacancy than the market should explain why.
• What rent growth is underwritten? Rents here rose 24.5% over five years. Ask whether the plan assumes that pace continues, and what happens to the deal if rents stay flat.
• How was the property tax bill estimated? A sale often triggers a reassessment, so the bill after purchase can be well above what the seller pays today.
• What capital work is budgeted? The median home in New Castle County was built in 1975, so roofs, plumbing and electrical systems deserve their own line items.
• How and when does capital come back? Ask what the plan is for a refinance or sale, and what happens if that takes longer than expected.

How Passive Investing In A New Castle County Apartment Syndication Works

Two groups make an apartment syndication work. The sponsor, or general partner, handles the deal: finding the building, financing it and running the business plan. The limited partners are passive investors who contribute capital and share in the property's results under the offering's terms.

Expect your money to be tied up for years, with no easy way to sell your share early, and remember that any investment can lose money. Most deals are open only to accredited investors under Rule 506(b) or 506(c). See investing with Skyline Capital for how we work with limited partners.
