The cheapest/simplest way I would recommend is using Excel spreadsheet.

When I sell/ flip I actually provide a " warranty" if there is a major issue, I will cover the cost.  

Charge what it costs, but I agree try to find something that is less expensive (eg $50).

That house will rent for less than $3,000 a month so you'll have nothing left to set aside for vacancies, property management, etc.Learn how to crunch numbers, then work with a professional that can help you understand the true costs of a market.

Then you can reinvest w/no 1031 stress.The step-up in basis provision adjusts the value, or “cost basis,” of an inherited asset (stocks, bonds, real estate, etc.) when it is passed on, after death.

The goal is highest rent for lowest investment cost and lowest maintenance.

Which would effectively reduce finance cost.And allows for other options such as offered by ROCusa.org (Resident Owned Communities).https://rocusa.org/whats-a-roc/what-is-a-roc-how-is-it-diffe...Together these options allow the residence to keep their costs within their own control, and continue to live where they are. 

The cheapest premium for an occupied property is now around $4,300.

It will end up costing you unless you're already a skilled contractor type individual.Get to know your neighbors that maybe around your property, especially if you're in a HOA situation where there's a mix of STRs and residential properties.

Property is cheap and the numbers look good on paper, but I think reality hits a lot of people like a sledgehammer with turnover costs, vacancies, problematic renters, maintenance, etc.
