I'm not sure the building will still be for sale long enough for me to sell these two buildings Scenario #2I keep saving until I have enough for another downpayment on another four family and continue to rinse and repeat this for years.

I personally think anyone with fewer than 20 units is wasting money by paying for software when a spreadsheet would do just fine.I recently tested TenantCloud (free for up to 75 units) and it has some really great features for a beginning Landlord, to include online marketing.

Preferably it would be the 4plex so that as cashflow is generated you can continue to work on the 5plex.
