The calculator has been updated with a few changes including better future analysis charts and graphs, better on-page instructions by hovering your mouse, and I tweaked a few formulas.

@Stan Lee I would look for money from friends and Family, or HML, or Partner with someone (I do not have details of the deal, and can't give a more precise advice) for down-payment.

My personal goal is to have an investment portfolio where 50% of it looks like the pie chart below and 50% of it is real estate.

They have a lot of functionality, but honestly there is a steep learning kill and is probably overkill for most rehabbers.TeamGantt/Gantter/MS Project - Gantt Scheduling Softwares for creating Gantt Charts & Timelines, & managing tasks.Trello/Zoho Projects/Basecamp - General project management software that includes tasks, Gantt scheduling, calendars, project forums, document storage & team collaboration toolsPodio - Customizable system that allows you to build workflows, track tasks, etc.Smartsheet/AirTable - Provide spreadsheet style platforms with additional functionalities for uploading documents/images, assigning tasks, calendar, images, etc...Office 365/Google Sheets I am currently beta testing my own Rehab Project Management platform that should be available soon that you are more than welcome to try out!

After you've developed a knowledge base I'd recommend posting more specific questions to get more precise answers.

The most precise and accurate way to calculate CapEx is to:List out all CapEx items for a particular property (Roof, A/C, furnace, appliances, flooring, hot water heater, etc...).Determine the approximate lifetime and replacement cost of each item.Determine the approximate useful life remaining for each item at the property.Aggregate this information to determine a monthly reserve amount.Obviously that's a lot of work, but it's an exercise that I recommend everyone who is new goes through at least once or twice on a property before making an offer.

This will help you be more precise with your numbers.
