What do I need to do to generate leads and close deals?

If your goal is only initial cash flow, almost any major metro with a declining population will meet this need.

My property generate 4100 per month and it is a 2 family.

However, ensure you have a solid repayment plan to avoid over-leveraging your home.Focus on long-term rentals that generate steady cash flow and offer tax advantages, such as depreciation and deductible expenses.

Since rental losses are typically passive, the best way to offset W-2 income is through Real Estate Professional Status (REPS) (750+ hours) or Short-Term Rentals (STRs) (100+ hours and more time than anyone else managing the property), which allow real estate losses, including depreciation, to offset active income.A cost segregation study accelerates depreciation, generating large upfront deductions.

Having said that, since you're a newbie my strong suggestion is to go thru a professional initially.  

Thank you @Jaycee Greene and @Hossein DaneshIn sum:- 42 apartment rental deal (land has potential to add 32 more on  two small building but that phase would be out of scope for this initial stage analysis).- Negotiated sales price $3.2 (seller financed)- 30% DP @ 7% / 20rs.

These properties would generate income, provide tax advantages, and appreciate in value until they were ready to retire.

Your initial terms will vary based on your investment experience, but generally, you want to plan on needing 20% of the purchase price if you're a newer investor and the lender will cover 100% of the rehab.

Partnering: If you're initially short on funds or experience, consider partnering with someone who has more experience or capital.
