I just acquired a duplex, and the tenant has been there 15 years and takes care of the place like it's her own.

Perhaps the system strategies are best in a buyers market, other states or for acquiring off market properties.  

Acquiring in cash or with a fix and flip loan.

From there, I would like to consider a 1031 exchange in the future to acquire more units.My current property management company suggested that they could handle a mid sized apartment building but I would absolutely not consider them for it as I believe they have overextended themselves and communication is lacking.

I would acquire in cash and then refi into longer funding. #4.

I am interested in acquiring a 10-acre lot with a house listed for $1.6M in a Houston suburb and would like to investigate financing options for building a commercial structure on the property.

Quote from @Devin James: When running numbers on an investment property, I focus more on equity growth than monthly cash flow.Here’s why:If I can acquire a property at a low basis and add significant value, I can: 1) Sell and reinvest elsewhere 2) Cash-out refinance to recapture my investment.

I was recently able to acquire a property that cash-flowed day one thanks to owner financing. 

1.Finding Value: Identifying properties with strong upside potential is critical in markets like Antioch.2.Rehab Management: Staying under budget and on schedule ensures better cash flow and quicker refinancing.3.Leverage Matters: The HELOC strategy allows me to scale quickly and acquire more properties without tying up personal capital.

I would like to acquire a 15 unit or so apartment.
