If you don’t have a large down payment saved up, don’t worry—there are plenty of options available . . .”A trusted lender will go over the various loan types with you, any down payment requirements on those, and down payment assistance programs you may qualify for.

Quote from @Pranav Patel: Hello,I'm 22 years old with roughly $50k saved up through part time jobs and internships.

I recommend two accounts: checking and savings.

Buyers who go directly to the listing agent will not see the same savings, if they see any savings at all.

It sounds like you’re in a great position to get started—$100k saved up and a clear goal are huge advantages.

Operationally, it's easier in multifamily and you'll have cost-saving opportunities as well when it comes to certain expenses.

Doing it in December will not save you any taxes anyway.

After some research online, I am reading that the cost per square foot on a gut renovation of this nature in Stamford CT is anywhere from $150-$350, which is ultimately not very helpful, because at $150 per sq ft, this is a very appealing project with a total profit of ~$175K (46% ROI) and at $350 per sq ft, it very much isn't, because it would be a net loss of 83K (haha).QUESTIONS:What can I do refine my estimate a bit given that I am not allowed to a formal inspection on the property? 

Examples could include:Partnering with other investors to share risk.Using seller financing or lease options.Leveraging creative rehab techniques to save on costs.Negotiating with contractors in a unique way to reduce expenses.I’d love to hear any stories, tips, or approaches that helped you pull off a deal others might have instantly passed on.
