I generally only use the anonymized email provided by the websites.

I've had low returns but in general all have made money.

I will answer as it relates to traditional BRRRR, in the general case there are additional options.  1) Do not perform maximum cash extract.  

Here is a list of potential options:Trello/Asana/Zoho Projects/Freedcamp/Basecamp/Workfront/Monday.com/Jira/etc,etc,etc,etc,etc - General project management software that includes tasks, Gantt scheduling, calendars, project forums, document storage & team collaboration toolsTeamGantt/Gantter/MS Project - Gantt Scheduling Softwares for creating Gantt Charts & Timelines, & managing tasks.Podio - Customizable system that allows you to build workflows, track tasks, track leads, etc.Smartsheet/AirTable - Provide spreadsheet style platforms with additional functionalities for uploading documents/images, assigning tasks, calendar, images, etcOffice 365/Google Sheets Spreadsheets - Believe it or not, a lot of successful flippers still manage their entire business in Microsoft Excel or Google Sheets. 

go to Home Depot, talk to some general contractors, join your local Facebook and meetup groups and start getting good ranges for every major item.

Market is not generally fast moving so having a good agent is key. 

Sure, generally I like the properties near the walkway over the hudson, near Marist or by Vassar Medical Center.

Here are some other strategies:Investor Networks: Share through local REI groups or investor meetups in Colorado and Ohio.Direct Outreach: Use mailing lists or email campaigns targeting known investors or real estate firms.Social Media: Post in real estate forums or Facebook groups for investors.Websites for Property ListingsRoofstock: Specializes in selling single-family rental properties to investors, offering built-in tools for analysis.BiggerPockets Marketplace: A hub for active real estate investors, perfect for promoting rental properties.Auction.com: If you’re open to auctioning properties, this platform reaches a broad investor audience.RealtyMogul: Offers connections to individual and institutional investors, especially for multifamily properties.MyHouseDeals: Focused on connecting with investors looking for fix-and-flip or rental properties.Zillow Rental Manager: While more general, it can still attract landlords looking to expand portfolios.Mashvisor: A great platform to market properties with detailed cash flow and rental projections.PropertyShark: Targets real estate professionals and investors with access to detailed property data.These can help you reach a broader audience and possibly sell faster.

For costs, you’ll typically need to budget for title insurance (usually around 0.5%-1% of the purchase price), attorney fees (varies but can range from $500-$2,000 depending on the complexity), and closing costs (might include recording fees, escrow fees, and other admin costs—generally $500-$2,000).

@Eva Sha - Yes, I generally advise emerging developers there will be anywhere from 5%-8% in closing costs (depending on the size of the loan), which include lender costs/fees, attorney's fees, and title fees, plus any other consulting fees.
