Find an investment property a duplex or 4-plex and build a model on purchase, rehab, and rental and then sale in 5 years. It covers all of the bases. Add coinop laundry to add to revenue. Use a local property for sale so you can find comps and do a quick market analysis. Use craigslist to get an idea of local rental rates. Ask a Realtor or Loan Officer to help with closing cost estimates. Tell the truth and they might help. Building cost estimates are easy. The inspection company Pillar to Post has a brochure of building cost estimates. Get a copy (pdf online?) and use those numbers for the rehab. Do a simple rehab of paint, carpet, and reface bathrooms and kitchen.
Sign up for a financial modeling course and when you sen them your model, let them know you are taking a basics course. Even financial planners sometimes build models in excel, so whatever job you get, you’ll need to know some basics to make life easier.
Have fun. If the numbers work out, this may be your first personal real estate investment opportunity. Or the model of what to look for when you have some savings, cash flow, and credit.
