You only need a place to track tenant information, payment history, maintenance, etc.

Carrying Costs and Contingency Funds - How do you estimate carrying costs, including taxes, maintenance, and interest, if the project spans several years?

I've been using Hostaway for a few years and generally like the platform and the support.We made a recent switch from Turno to Breezeway for better vendor/maintenance coordination.

But in reality, reinvestment risk is real.In rentals, in today's market, there is basically no cashflow available after a BRRR and you introduce tenant risk into the equation and any longterm hold will have pretty continual maintenance.  

I have to budget for other expenses (repairs, maintenance, etc.) out of pocket.We are coming from Seattle which is a more expensive market and we have the cash to be able to do this, but I hear your pain - when you are starting out, that might not be a good idea.  

Making the tenant responsible for any maintenance is generally a bad idea.

It is too much for one person while trying to handle some of the maintenance myself, leasingand property management.   

Worst case is hard to predict of course but I guess you end up losing the place or paying them a lot of money as in cash for keys.How would you handle maintenance?

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

That's actually a comedy routine to an experience investor.
