I would discuss this with your accountant.

Rufo  Also consider the fact that when you switch from STR to LTR or the other way around, you will need your CPA/tax professional to do the IRS' 3115 change of accounting form to go from 39-year depreciation for STR to 27.5-year depreciation for a LTR.

And it's convenient for life if you use your personal bank account, you can still have one app for rentals and paying friends.-  Con's:  Nothing about the software per say, but about the landlord experience. 

The 25K would go towards a rate buy down.As far as accounting for cap ex and maintenance for newly replaced/updated items, I'd still recommend doing it.

If entities are disregarded, you can keep up with more than 1 in a single QBO account using the location/business feature to keep track of them separately.

Since the account is linked to your mortgage, overspending can increase mortgage balances instead of paying them down.

Built-in accounting software, keeps track of everything better and helps for tax returns at the end of the year3. multiple payment options are usually available for residents4. maintenance requests all in one area, easier to keep track of and keep residents informed of the status5.

Then additional expenses for virtual assistants, legal help, accounting, etc.  

@Philip Jones we've helped our clients do over a hundred.As some of the lenders posting have pointed out, the challenges are:1) Property value and corresponding loan size2) Appraisals have much better comparables than 5 years ago, but may still be an issue.3) Property condition can be an issue via the appraisal4) Ownership seasoning - most lenders looking for 6+ months or incredible documentation for cost of improvements made.5) Most DSR lenders require professional property management.Always try a small local bank or credit union, but most will expect you to transfer your business bank accounts over to them. 

@Andres Triveno, operating the LLC 100% means that we sign contracts and other documents as member or manager of the LLC instead of using our own names, we have a business phone instead of using our personal phone, we have a business checking account for business spend.
