These platforms typically have billing policies where you pay a per unit fee per month to the software and you get regular updates and support each month.There are a number of low-cost platforms available that are able to offer you a lower price by passing along some of the costs to your tenants (payment processing fees, applications, tenant screening, etc).

We'll certainly want to keep the property tax basis as low as possible if we hold it.

The problem is: A traditionally financed low-down payment house-hack with traditional long-term rents simply won't cash flow during occupancy, or after, in many MCOL-HCOL markets in the US. 95% leverage at even 5.7% just won't work in a lot of cases right now.

Can you tell us what your fees are for this loan to achieve such a low rate? 

I'm currently renting and when  decided I wanted to focus on real estate investing, I decided not to buy in Tampa because of the low MF inventory and in home house hacking is not for me.

Cost to build is $350K (I am managing it all myself and calling in favors around the city to get low rates on materials and labor).

An 80% occupancy rate indicates low demand. 

They didn't actively advertiseour home on websites and we had low tenantresponse.

I assume you currently have a residential mortgage that does not have a pre-payment penalty.

Most of my CFO clients that are in residential development are looking for IRRs (usually over a minimum 5-year period) in the high teens and the commercial developers are looking in the low to mid 20% range.
