Through this journey, I’ve built strong relationships and developed valuable expertise in:Researching micromarkets and identifying comparables, potencial Accurately estimating construction or remodeling costs.Securing fast and reliable financing through partnerships with two top hard money lenders in Texas, offering competitive rates.I’m on this platform to connect with capital partners who are seeking an annual ROI of 12%-15%.
