Hi @Ravi Karuturi
Lenders will look at your overall teams experience in executing on the project. Also they would like to see you have some skin in the game, which it sounds like you are working on.
Regarding the LTC (loan to cost) this will vary depending on your funding source (bank, private equity, etc.). But the example you gave, I would estimate $3M as a good starting point for the project.
Your post liquidity also will be looked at as well.
I would recommend partnering with people that compliments areas you may not be strong at for your project. If this is for experience you may want to partner with someone that has completed several similar projects. Or, if you don't have experience managing a multifamily property post construction that could be something to look at. Same with your liquidity. This all helps, and goes into your sponsor/guarantor bio for the project which lenders almost always request this.
You can network on here BP, local chamber of commerce, builder associations, join local meetup events to find like minded individuals to help find that partner.
