@Raj G.that's a great problem to have! With very little extra info about your ability to take loans, length of time you intend to hold on the properties, how much time to intend to devote finding, remodeling, and renting the units, here's the plan I would advise.
I would invest in a number of 3-4 unit buildings and lock in 25% down conventional loans. While 1 million dollar sounds like a lot, after putting aside about 100K for reserves and if you need another 100K for improvements of the properties you'll buy, you'll have enough money left to buy only about $3,200,000 in properties, which depending on what neighborhoods you'll buy will translate anywhere between 4-8 buildings.
Why buy three-four flats? Because of at least four reasons:
1. FINANCING - Lock in the historically low interest rates for 30 years fixed mortgages, which for investors are around 3.2%. If you were to buy commercial buildings, the rates will be higher and your return will significantly change when you'll have to refinance that building.
2. RESALE VALUE & ASSET DISPOSAL - 3-4 unit buildings are the easiest to resell if you want fast cash due to the fact that most buyers can buy them with $0 down, VA loans or 3.5%down FHA loans, and a lot of investors will scrape together the 25% down for a building under 1 million dollar. In other words: EASY TO RESELL FOR TOP DOLLAR. Plus you won't need to liquidate all your properties if you need only a couple hundred thousand versus having to sell your commercial property.
3. PROPERTY & TENANT MANAGEMENT - I call it Tenant Management as a lot of time the tenants moving in smaller buildings stay longer in the properties, and these buildings are easy to self-manage as most units have separate utilities, so fewer bills and less tenant turnover
4. APPRECIATION - This type of buildings have had the tendency to go up in value faster than single-family homes & even commercial buildings due to the fact that when you raise rents, you do it for 3-4 units at a time, which automatically raises values
Good luck to you and reach out if you need further strategizing!
