@John RinggoldI retain 50% of the deposit for redecorating expenses for the last 11 years.

I'd love to get into a market with lots of property options so I can scale and retain the property management and contractors.

Treat it as an expense for your "use of cash" projections and savings or retained earnings.

From what I've observed, single families may or may not have the necessary margins.

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

This helped me keep some of my cash out on LOW interest (2.99% to 4.99%).These two things helped me retain the LTV's and some income to help (not cure) the issues I had with banks until my properties could establish long term income of their own. 

@Shehzad S.I agree with some of that but I am still interested in observing regional trends.On a whole I think that, in the right hands, data is definitely an asset and not a liability.

To find comparables in your area, an average person can do the following:Research online: Websites such as Zillow, Redfin, and Realtor.com provide home values and information on recently sold properties in a specific area.Check public records: Property records are available online or at local government offices and can provide information on sales prices, property size, and other details about recently sold homes in the area.Ask a real estate agent: A real estate agent can provide information on recently sold properties and help interpret the data.Drive around the neighborhood: Observing properties in the area can give you a sense of the types of homes and their condition.Consider the local market conditions: Take into account factors such as the current real estate market trends, demand for housing, and the local economy when evaluating comparables.Note: It’s important to choose comparable properties that are similar to the subject property in terms of size, location, age, and features, as these factors can greatly impact the value of a property.

You, as seller still retain personal liability for the loan should the buyer default.

In certain areas, simply observing the neighborhood when your agent shows you the house is not sufficient in my opinion.
