I want to add him to 50% ownership so we can both manage the property and access the cash flow.

I would greatly appreciate feedback from those with experience in property management or similar challenges.

Typically about 75-125 people in the room and probably half or more own or manage rentals. 

Many large financial institutions are fond of the build-to-rent industry because demand for housing is strong and because new constructions require less maintenance and are a more predictable investment than older homes.

I think it would be a good candidate for mid term rentals, but I don't want to manage it.

Here’s a detailed breakdown of these two types of markets and the factors that contribute to each:Cash Flow Market, a cash flow market is one where rental income exceeds the expenses of owning the property (mortgage, taxes, insurance, maintenance, and property management), resulting in positive monthly cash flow for the investor.Key Characteristics:High Rental Yields: Properties typically have high rental yields compared to their purchase prices.Stable or Slow Appreciation: Property values increase slowly over time, if at all.Lower Property Prices: Generally, property prices are lower, making it easier to achieve positive cash flow.Higher Rental Demand: Strong demand for rentals due to economic factors, demographics, or local employment conditions.Factors Contributing to Cash Flow Markets:Economic Stability: Stable job markets and steady local economies that support rental demand.Rental Market: High percentage of renters compared to homeowners.Affordability: Affordable property prices relative to rental income.Local Policies: Landlord-friendly laws and regulations.Appreciation Market, an appreciation market is one where property values increase significantly over time, offering substantial capital gains upon sale, but rental yields may be lower, resulting in lower monthly cash flow.Key Characteristics:High Property Value Growth: Significant annual increases in property values.Lower Rental Yields: Rental income may not cover the monthly expenses, leading to lower or even negative cash flow.Higher Property Prices: Generally higher property prices, which can make it harder to achieve positive cash flow.Strong Economic Growth: Rapid economic growth, population influx, and development.Factors Contributing to Appreciation Markets:Economic Boom: Strong local economy with job growth and high-paying industries.Population Growth: Influx of people moving to the area, increasing demand for housing.Infrastructure Development: Significant investments in infrastructure, amenities, and services.Desirability: High quality of life, good schools, and attractive neighborhoods.I hope this information finds you well. 

In the last 3 months we've had several prospects send us proof that someone we don't know, contacted them about a property we manage.

Self managing or using a property manager?

I am a local investor, broker, and own a property management company.

Also, consider reaching out to local property management companies for their input on rental demand and market conditions.Comparative Market Analysis (CMA): Your agent’s assertion about good rental comps should be backed by a Comparative Market Analysis.
