It also a property management piece built in with lease management functionality and maintenance requests. 

You only need a place to track tenant information, payment history, maintenance, etc.

Make sure both properties have all the repairs and maintenance needed and no major cap ex is needed before you try to add one on double leverage.

With a full time job even 15 units gets tough between collecting rent keeping repairs up, preventative maintenance, looking for new deals, managing refinances, etc. 

Because of this, I'm exploring what it would look like to begin investing in vacation rental real estate as a way to:1 - Save on taxes by taking depreciation2 - Hold long-term appreciating assets3 - Have properties where we enjoy vacationing that we can stay at when we go to do maintenance (probably 2 areas).What resources would you recommend for someone just starting out who has these specific goals?

However, it wasn’t clear if lawn care, snow removal, and ongoing maintenance costs are included, as they were initially listed as $0.I’ll clarify with the seller exactly what’s included in their reported expenses to ensure we have a complete picture of recurring costs and any potential gaps.the seller dropped the price from 798k to 645k.

You will always have taxes and insurance and maintenance and capex anyway, so how much better will you sleep because you eliminated one of those expenses?

Here's some other copy & paste advice you might find useful:---------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

It's free, handles rent payments/reminders/late fees, maintenance requests, some reporting (e.g., P&L), tracking expenses and income, rental listings, lease signing, etc. 

It comes down to what your pro forma is, and what lenders are willing to lend on the property.75k per unit for 550 in rents in Dayton is probably over valued, especially if there is deferred maintenance.
