How do we determine how much money to put aside for taxes?

Like others have said, you’d need to check out the municipal laws and run your numbers to make a determination about the viability of an STR in that space.

I would expect it to be standard practice to do a review of all the units and determine repairs needed, what monthly/yearly maintenance should be completed, and a rent analysis to set expectations for vacant rooms.  

Population growth, income growth, job growth, job diversification and rent growth can be good filters to help determine target markets.

We find our best tenants by posting ads at supermarkets.I can't tell much from the numbers you post since I don't think you mentioned your equity and that can help to determine whether or not you can sell what you have and upgrade to one more-profitable multi-unit property.

I'm gonna look into it here, once all the smoke settles.And lastly, the "short version" just referred to the detail in the post, I've posted on BP before and been told I left out crucial things such as details with numbers for someone to determine if a deal made sense financially or not so I originally typed up a whole manuscript, lol.

If a landlord, an agent, or other person acting under the landlord's direction or control, in possession of a tenant's personal property, fails to allow the tenant to retake possession of the property within 24 hours after written demand by the tenant or the tenant's duly authorized representative or within 48 hours, exclusive of weekends and holidays, after written demand by the tenant or a duly authorized representative when the landlord, the landlord's agent or person acting under the landlord's direction or control has removed and stored the personal property in accordance with subdivision 1 in a location other than the premises, the tenant shall recover from the landlord punitive damages in an amount not to exceed twice the actual damages or $1,000, whichever is greater, in addition to actual damages and reasonable attorney's fees.In determining the amount of punitive damages the court shall consider (1) the nature and value of the property; (2) the effect the deprivation of the property has had on the tenant; (3) if the landlord, an agent, or other person acting under the landlord's direction or control unlawfully took possession of the tenant's property; and (4) if the landlord, an agent, or other person under the landlord's direction or control acted in bad faith in failing to allow the tenant to retake possession of the property.The provisions of this subdivision do not apply to personal property which has been sold or otherwise disposed of by the landlord in accordance with subdivision 1, or to landlords who are housing authorities, created, or authorized to be created by sections 469.001 to 469.047, and their agents and employees, in possession of a tenant's personal property, except that housing authorities must allow the tenant to retake possession of the property in accordance with this subdivision.Subd. 3.Storage.

BP team-A deal on a SFH in Florence, SC to fix and flip has hit my desk (can expect $15k+ in profit), however I am trying to determine if I can convert this to a duplex or multifamily.

But at the same time there aren't many active comparable rental properties nearby, which makes determining the market rent of a property difficult.I found that using rental listings that are inactive but were recently active provides me with a lot more data for determining market rent.To do this I go to the Zillow rent estimator tool and enter my property's address as well as a (very) rough estimate of the rent.

Also, how will be able to determine what the taxes are there?
