Between a 1031 Exchange, HELOCs, and a partnership, I'm up to 15 doors including my personal residence.

What factors should I consider when making this decision?

Interest rates and cap rates change, competition changes, your PM ends up being horrible, lots of variables.Just to throw you a monkey wrench, in your killer spreadsheet does it include the credit score, income, and employer of every resident? 

., I think there's a lot to building a "community" like feel for your tenants that may include events, giveaways, etc., to get them to engage with you and elevate their living experience.  

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Include a buyout clause allowing you to transition to sole ownership after two years, based on a pre-determined valuation formula or market value.Use an LLC to hold the property for liability protection and pass-through taxation, ensuring both partners benefit from depreciation to offset rental income.

Part of those cuts included the short-term rental tax loophole, a strategy real estate investors can use to help mitigate their rental income tax by offsetting earned income with real estate losses, and could be renewed or extended.  

They have nice looking direct booking sites, but I'm more curious about their digital marketing training and crm software included with their package. 

I have spreadsheets filled with material lists for every phase of the build that includes pricing for materials as well as labor, and sources that I use for them.
