Hello,I am a Software Engineer and a Real Estate Investor working on a tech product for the real estate mortgage brokers.

I would not dump $500K into the mortgage to refinance.

Knowing your long-term plans can help you build a long-term financing strategy so that you are not just worried about purchase number 4, but also purchases 5 - 20+ (if you plan to continue to invest).I'm an investor and licensed mortgage broker.

Landlords can easily do it without a mortgage but they are taking a huge risk.

I'm looking more for an overarching portfolio spreadsheet to track asset performance over the lifetime of holding the asset.If you have the property manager paying the mortgages, taxes, insurances, doing all the accounting, etc why not just ask them to generate whatever report you want?

Marketing to find what is a deal, $$ to fund that many deals along with utilities, mortgage payments, taxes, cost overruns, etc.

Why not just advertise it as a 4 bed/4 bath and promote the apartment as its own private suite? 

The idea is simple: purchase a property, live in one part, and rent out the rest to offset your mortgage or even generate profit.
